💑 C++ Classes and Objects – Shaadi Wala Rishta Samjhi ke Seekhi! 🎉

"Class ek rishta ke format ba, aur object us format ke ladka-ladki!" 😄
"Jaisan biodata me sab kuch likhal rahaa, lekin asli kaam tabhi hota jab object banela – matlab rishta tay ho jaaye!"

📦 Class Aur Object Ka Logic Bhojpuri Me:

• Class – Biodata / Template
• Object – Real ladka ya ladki jo us class ke format ke base pe taiyaar ho jaata
• Member Variables – Naam, umr, height (jaise biodata me hota)
• Member Functions – Kya-kya kaam kar sakat baa (jaise cooking, job, driving)

🔰 Code Example – Shaadi Ka Biodata Banawat:

#include <iostream>
using namespace std;

// Class: Rishta ka Biodata
class Rishta {
public:
    string naam;
    int umr;
    string kaam;

    // Function to display biodata
    void dikhawa() {
        cout << "Naam: " << naam << endl;
        cout << "Umr: " << umr << endl;
        cout << "Kaam: " << kaam << endl;
    }
};

int main() {
    // Object: Ladka ka Rishta
    Rishta ladka;
    ladka.naam = "Guddu Kumar";
    ladka.umr = 24;
    ladka.kaam = "Software Engineer";

    // Object: Ladki ka Rishta
    Rishta ladki;
    ladki.naam = "Pinky Yadav";
    ladki.umr = 22;
    ladki.kaam = "Doctor";

    cout << "👨 Ladka ke Biodata:\n";
    ladka.dikhawa();

    cout << "\n👩 Ladki ke Biodata:\n";
    ladki.dikhawa();

    return 0;
}

🟢 Output:

👨 Ladka ke Biodata:
Naam: Guddu Kumar
Umr: 24
Kaam: Software Engineer

👩 Ladki ke Biodata:
Naam: Pinky Yadav
Umr: 22
Kaam: Doctor

🧠 Bhojpuri Samjhauta:

Concept	Bhojpuri Meaning
class	Rishta ka format (jaise biodata)
object	Real ladka/ladki (rishta candidate)
variables	Naam, umr, kaam
functions	Kaam bataye ke tareeka (dikhawa)
object.function()	Rishta dikhawat baa!

🤣 Bhojpuri Joke:
"Class toh sirf biodata rahaa, object banane ke baad hi rishta final hoyi!"
"Guddu ke object ban ke jab Pinky ke samne gaya, tabhi Pinky ke mummy khush bhaili!" 😂

🧠 Dynamic Memory Allocation in C++ – Hostel Wala Jugaad Seekhi Bhaiya! 🛏️🍜

💡 C++ me jab memory static tareeke se allocate karela (jaise ghar me mummy ke tiffin fix size ke), tab array ka size fix rahela. Lekin jab memory dynamic allocate karela, tab man marzi ke size ka dabba banawat bani — aur yeh sab new aur delete se hote baa!

📦 Real-Life Analogy:

Imagine karo:
👩‍👦 Mummy har subah ghar me fix size ka tiffin banawat rahali – chahe bhook lagela ya na.
🥲 Lekin hostel me toh bhaiya, apne hisaab se banawat bani – kabhi 2 roti, kabhi 10 Maggie packet. Aur kaam ho jaaye to bartan khali kar ke side me rakh dete hain!

Yahi logic baa C++ me new aur delete ka!

🔰 Basic Syntax:

int* ptr = new int;       // ek integer ke memory allocate karo
*ptr = 10;                // usme value daal do
delete ptr;               // memory khali karo

🧠 new se memory ka jugaad hota baa
🧹 delete se memory free ho jaat baa – warna memory leak ho jai!

🎯 Example: Hostel ke Maggie System

#include <iostream>
using namespace std;

int main() {
    int n;
    cout << "Kitna Maggie packet chahiye bhaiya? ";
    cin >> n;

    int* maggie = new int[n];

    for (int i = 0; i < n; i++) {
        cout << "Price of packet " << i + 1 << ": ";
        cin >> maggie[i];
    }

    cout << "Tumhare Maggie Packet ke Prices: ";
    for (int i = 0; i < n; i++) {
        cout << maggie[i] << " ";
    }
    cout << endl;

    delete[] maggie;

    return 0;
}

🟢 Sample Output:

Kitna Maggie packet chahiye bhaiya? 3
Price of packet 1: 12
Price of packet 2: 15
Price of packet 3: 10
Tumhare Maggie Packet ke Prices: 12 15 10

🧠 Bhojpuri Soch:

Concept	Bhojpuri Samjhauta
int* ptr = new int;	Hostel me ek plate Maggie ka order
*ptr = 10;	Usme 10 rupiya ke masala daal ke ready
delete ptr;	Khana ho gaya, plate dhoke side me!
new int[n];	Kitna bhook lagal baa, utna packet banwa lo
delete[] ptr;	Sab packet khali karo, aur plate wapas karo

🤣 Bhojpuri Joke Time:
"Mummy ke ghar me tiffin fix size ke milat baa, lekin hostel me new ke bharosa par jeewan chalela!"
"Aur agar delete na karela, toh memory leak hoke Maggie bhi RAM me atak jaayi!" 🤯

📸 Internal Visualization:

int* ptr = new int;    // heap me ek memory milal
*ptr = 20;             // usme 20 daalal
delete ptr;            // free kar diye – hostel ka plate dhul gaya

⚠️ Caution Box – "Memory Leak Warning"
Agar new se memory leke delete na karela, to RAM bhar jaayi. Jaise hostel me plate dhulwana bhool jaaye – agli baar khana serve hi na ho!

🧠 Summary:

"Dynamic memory allocation ka matlab baa – jitna chahiye, utna memory le lo (new)… aur kaam ho jaaye to wapas kar do (delete). Yahi hai asli hostel life logic!" 😎🍜

🚀 Function with Pointers in C++ – Zomato Delivery Style me!

💡 Function with pointers ka matlab baa: ek function jo pointer ke through data receive kare, update kare aur direct delivery ke jaise value change kar de! Samjho ek delivery boy ke paas address aa gaya aur usse order update kar de.

🔰 Basic Concept:

C++ me jab hum pointer ke through function me value pass karat bani, tab function asli value ke address se kaam karta baa – matlab asli value update ho sakta baa! Aisan hi samjho: Zomato ke app me order de rahe hai, aur restaurant se order me thoda modification chahi – wo update ho jai directly!

🔍 Code Example: "Order Update Function" 🍱

#include <iostream>
using namespace std;

// Function jo pointer se value receive kare ke kaam karela
void updateOrder(int* orderAmount) {
    // Thodi delivery fee add kar diye – value update kar diye jaise bonus tip!
    *orderAmount = *orderAmount + 50;

    // Punchline:
    cout << "Order update bhaiya: Ab order amount ho gaya: " << *orderAmount << " Rs" << endl;
}

int main() {
    int order = 250;  // Initial order amount
    cout << "Pehle order amount: " << order << " Rs" << endl;

    // Function ko order ke address pass karat bani
    updateOrder(&order);

    cout << "Final order amount (after update): " << order << " Rs" << endl;
    return 0;
}
  

🟢 Output:

Pehle order amount: 250 Rs
Order update bhaiya: Ab order amount ho gaya: 300 Rs
Final order amount (after update): 300 Rs
  

🍽️ Bhojpuri Analogy:

• Order ke pehla amount: 250 Rs – Jaisan customer ne order place kia.
• updateOrder() function: Restaurant wala function – jiska paas order ka address hai aur jisme kuch extra charges (delivery fee) add kia jaata.
• Final order amount: Badha ke 300 Rs – Direct update ho gaya order ke value!

😆 Joke Time:
"Jab pointer se function ke call hota, restaurant ke manager bole: 'Order me thoda twist add kar dete hain, bonus tip samajh ke!'"

📌 Key Points:

• Call by Address: Function me pointer ke through call karke asli value ko update karte hai.
• Efficient Delivery: Jaise delivery boy order ko directly customer ke ghar le ke jata, waise hi pointer function me value ko directly manipulate karta baa.
• Memory Ka Khayal: Pointers se function efficient banta, lekin dhyan rahe – address pass karna matlab asli data ke saath khelna!

Pointer to Pointer in C++ – Dubara Delivery Boy Wala Logic!

– Ab delivery boy ke paas ek aur delivery boy ke address ba! 😄🍴

---

😵‍💫 Sochi Bhaiya – Ek Delivery Boy, Dusra Uske Sath Aur GPS leke!

💡 "Pointer to pointer" ek aisan concept baa ja hamar Zomato ke delivery boy ke hierarchy samjhi. Pehla delivery boy ke paas dusra delivery boy ke address baa, aur dusra delivery boy ke paas thali ke location baa! 😆

---

🎯 Real Life Example – Zomato ke Bhaiya aur Uska Chhota Bhaiya 📦

Imagine karo ek Zomato ke senior delivery boy ke paas ek naya trainee delivery boy baa.
Senior sirf trainee ke location ke jaane – aur trainee actual thali leke customer ke ghar jaa raha baa.

🔰 Syntax samjhi:

int value = 100;
int* ptr = &value;
int** ptr2 = &ptr;

value — actual thali
ptr — trainee delivery boy (jiske paas thali ke address baa)
ptr2 — senior delivery boy (jiske paas trainee delivery boy ke address baa)

🔍 Breakdown:

Variable	Kaun baa?	Kya rakhal baa?
value	Thali	100 rupees ka khaana
ptr	Trainee	Thali ke address
ptr2	Senior	Trainee ke address

📦 Access kaise kare?

cout << value << endl;    // 100
cout << *ptr << endl;     // 100
cout << **ptr2 << endl;   // 100

Ek line me punchline:
Senior bolta: "Chhota bhaiya ke puchho, u thali leke gaya baa!" 😎

🤖 Visual soch lijiye:

value   ---> 100
ptr     ---> &value
ptr2    ---> &ptr

*ptr     ---> value
**ptr2   ---> value

🤯 Confusion Level = Office Politics

Kabhi lagta: "Yeh pointer kisko point kar raha baa?"
🔁 Jab samajh jaayi ki pointer bhi ek normal variable baa jisme address rakha jaat baa – sab easy ho jaayi!

👨‍🍳 Analogy – Kitchen Order Management 🍽️

Imagine karo:

1. Customer: "Biryani chahi!"
2. Chef (value): Biryani banata
3. Waiter (ptr): Chef se leke table pe laya
4. Manager (ptr2): Sirf waiter ke track karta baa 😁

Aur jab Manager bole: "Dekha to waiter kahan baa aur uske haath me ka ba?"
To **ptr2 se Biryani mil jaat baa!

🧪 Full Code:

#include <iostream>
using namespace std;

int main() {
    int thali = 250;
    int* trainee = &thali;
    int** senior = &trainee;

    cout << "Customer ko mila: " << **senior << " Rs ka thali" << endl;

    return 0;
}

🟢 Output:
Customer ko mila: 250 Rs ka thali

📌 Note for Baccha Log:

Baccha log suno!
int** ptr2 ka matlab baa: ek pointer jo ek aur pointer ke address rakhta baa.
Use **ptr2 likh ke actual value (jaise thali ka price) nikala jaa sakta baa!

💡 Real World Programming Use:

• 2D Arrays ke saath
• Dynamic memory allocation
• Function jo pointer leke aaye aur return bhi kare

😂 Bhojpuri Punch:

"Pointer to pointer aisan hi baa jaise hero ke paas villain ke chamcha ke address ho – direct nahi maarat baa, pehle chamcha ke khojat baa!" 😜

Pointer with Arrays in C++ – Zomato Wala Logic samjhi Bhaiya!

💡 C++ me pointer aur array ke rishta kuch aisan baa jaise Zomato ke delivery boy aur uske route map ke beech. Thali kahan jaayi, kaun dish kahan rakhal baa – sab kuch pointer samhale baa!

---

🔰 Basic Syntax:

int arr[5] = {10, 20, 30, 40, 50};
int* ptr = arr;

arr ek thali baa jisme 5 item rakhal baa.
ptr ek delivery boy baa jiske haath me map baa ki kaun item kahan baa.

---

🧠 Note:

arr ka naam hi ek pointer ke tarah behave karela. Yani arr ka matlab hota: "pahila item ke address."

---

🍛 Let's break it down:

int arr[5] = {10, 20, 30, 40, 50};

🧾 Thali me 5 item rakhal baa:

Index	Item
0	10
1	20
2	30
3	40
4	50

---

📦 Step 1: Pointer se array handle karo

int* ptr = arr;

ptr ek delivery boy baa, jiske paas location baa ki arr[0] kahan baa.

---

🍲 Step 2: Access kaise kare?

cout << *ptr << endl;      // 10
cout << *(ptr + 1) << endl;  // 20
cout << *(ptr + 2) << endl;  // 30

➡️ Delivery boy ke paas ek list baa, aur *(ptr + i) se u thali me i-th item ke plate khola jaat baa!

---

😍 Shortcut with loop:

for (int i = 0; i < 5; i++) {
    cout << *(ptr + i) << " ";
}

📦 Output:
10 20 30 40 50

🔁 Matlab delivery boy har ghar jaat baa aur har thali ke item dikhat baa!

---

📸 Internal Soch:

arr     ---> &arr[0]
ptr     ---> arr
*ptr    ---> arr[0]
*(ptr+1) ---> arr[1]

---

🔍 Can we do this?

ptr = &arr[2];
cout << *ptr;   // 30

➡️ Bilkul! Delivery boy route ke bich me bhi enter kar sakta baa – sidha 3rd item se delivery start karwa do!

---

⚠️ Pro Tips:

Code	Bhojpuri Soch
arr[i]	thali ke i-th item
*(arr + i)	pointer se i-th item
ptr[i]	pointer se bhi array style me access ho sakta baa!

---

📦 Full Example:

#include <iostream>
using namespace std;

int main() {
    int arr[5] = {5, 10, 15, 20, 25};
    int* ptr = arr;

    for (int i = 0; i < 5; i++) {
        cout << "Delivery to house " << i << ": " << *(ptr + i) << " Rs thali" << endl;
    }

    return 0;
}

---

🧠 Summary:

💡 Array ek thali baa, aur pointer ek delivery boy baa. arr pointer ke tarah behave karela. Pointer arithmetic se array ke har item tak pahuch sakat bani. Aur *ptr se uska value nikal sakat bani. 😎

📦 Pointer Basics in C++ – Bhojpuri Style (Dubba aur Chashma Wala Example)

🧠 Code:

int x = 10;
int* ptr = &x;

🔎 Ka kahani baa?

🪣 Step 1: x naam ke ek dubba banawa

int x = 10;

➡️ Matlab: Tu ek dabba (variable) banawle baa jiska naam x baa, aur u dabba me 10 ke value rakhal baa.

Jaise: "x" ek thaila baa jisme 10 rupya rakhal baa.

🪣 Step 2: ptr ek dusra dubba baa — lekin isme paisa na, balki pata baa!

int* ptr = &x;

➡️ Matlab: ptr naam ke ek pointer-dabba baa, jisme x ke address rakhal baa.

Sochi: ptr ek duniya ke map baa, jisme likhal baa – "x waala ghar yehan baa!"

🕶️ Ab *ptr likh ke kya karatani?

Jab tu *ptr likhela, matlab tu chashma laga ke uss address waala ghar ke andar झाँक रहल बा – aur dekhat baa ki value ke baa?

cout << *ptr;  // Output: 10

➡️ Matlab: Chashma laga ke tu ptr ke andar ke address pe jaat baa, aur wahaan tu dekhat baa – "Arre! 10 rakhal baa!"

📦 Ek Line Me Kahani:

• x = Paisa wala dubba
• &x = Us dubba ke location
• ptr = &x = Location ek naye dabba me rakhal baa
• *ptr = Chashma laga ke uss jagah pe jake value dekhna

🎨 Visual sochi:

x -------> [ 10 ]
ptr -----> [ address of x ]
*ptr -----> 10 (value at x's address)

🧪 Ek example aur:

int a = 20;
int* p = &a;

cout << a << endl;     // 20
cout << &a << endl;    // address (e.g., 0x61ff08)
cout << p << endl;     // same address (0x61ff08)
cout << *p << endl;    // 20

Chashma laga ke p ke andar jake value dekhlo – wahi a ke value baa!

📌 Important:

Syntax	Matlab (Bhojpuri)
int x	Ek dubba bana ke 10 rakhl ba
&x	U dubba ke location
int* p	Ek naya dabba jo location rakhe
p = &x	p dabba me x ke location dal dehal
*p	Chashma laga ke p ke location par jakar value dekhna

🔚 Summary:

Jaise ghar ke address se koi delivery ho jaala, waise hi pointer ptr ke paas address baa, aur *ptr chashma laga ke wahaan se value utha ke laawe la!

🤯 C++ String Functions – Jab Manager Anmol Ji ke Breakup ka Analysis Guddu kare :substr() se!

---

☕ Kahani Ki Shuruaat – Breakup, Email aur String Functions

📅 Monday Morning
👔 Guddu office pahunchal, mood me tha. Suddenly...

👨‍💼 Anmol Ji:
"Guddu, ek breakup email milal baa. Uhe ka analyse karo. Kahe ki string function sab seekha ke mauka milal baa!"

😅 Guddu samjhal – ee to sir ke dil ke dard ke debug kare ke assignment baa!

🧠 Important String Functions in C++

1️⃣ length() / size()

Kaam: String ke total characters gin ke batave
Syntax: str.length() ya str.size()

string msg = "I miss you";
cout << msg.length();  // Output: 10

🫣 Sir: "Breakup mail me 10 words me dard chhupal baa!"

2️⃣ substr(pos, len)

Kaam: String ke ek tukda nikaale
Syntax: str.substr(start_position, length)

string msg = "I miss you badly";
string pain = msg.substr(10, 6);
cout << pain;  // Output: badly

😔 Guddu: “Ee ‘badly’ word me hi sab kuch baa sir!”

3️⃣ append() / +=

Kaam: Do string ke jod de
Syntax: str1.append(str2) ya str1 += str2

string a = "I ";
a.append("quit");
cout << a;  // Output: I quit

🥲 Sir: “U quit?? To company bhi tujh par append kar diye: ‘Access Denied’”

4️⃣ insert(pos, str)

Kaam: Beech me kuch daale
Syntax: str.insert(position, "text")

string a = "GudduGood";
a.insert(5, "Boy");
cout << a;  // GudduBoyGood

🤣 Guddu: “Sir, ego ‘Boy’ insert kar diye, to image clean ho gaya!”

5️⃣ erase(pos, len)

Kaam: Kuch hissa hata de
Syntax: str.erase(position, length)

string a = "I still love you";
a.erase(2, 6);
cout << a;  // I love you

💔 Sir: “‘still’ hata diye... emotional baggage erase!”

6️⃣ replace(pos, len, str)

Kaam: Ek part ke dusra se replace kar de
Syntax: str.replace(position, length, "new")

string a = "I hate you";
a.replace(2, 4, "love");
cout << a;  // I love you

🥹 Guddu: “Sir, patch-up ho sakta baa, code proof baa!”

7️⃣ find() / rfind()

Kaam: Text kaha baa string me, batave
find(): pehla match
rfind(): last match

string msg = "Sorry sorry sorry!";
cout << msg.find("sorry");   // 6
cout << msg.rfind("sorry");  // 12

🧘 Sir: “Client bhi har baar same bug find karata, rfind karke bhi!”

8️⃣ compare()

Kaam: Dono string barabar baa ki na, check kare
Returns: 0 = equal, >0 or <0 = not equal

string a = "Love";
string b = "Hate";
cout << a.compare(b);  // Negative

🥶 Sir: “Ee comparison se hi decision aayi ki relation move on ho jaayi!”

9️⃣ clear() + empty()

clear(): string ke khali kar de
empty(): check kare khali baa ki na

string msg = "Bye";
msg.clear();
cout << msg.empty();  // Output: 1 (true)

😶 Sir: “Jaise Gmail inbox clear kar diye, dil bhi khali…”

🔟 c_str()

Kaam: C-style string return kare (const char*)
Useful jab C library ke sath kaam karat baani

string s = "Guddu";
const char* ch = s.c_str();

🧠 Bonus Tip – String Concatenation

string first = "Hello";
string last = "World";
string result = first + " " + last;

📢 Guddu: "Sir, life me jab string jaisan combine ho jaayi, tabhi syntax correct lagela!"

🔚 Conclusion

String function ke duniya kuch emotional hoti baa.
Kabhi erase() kare ke padta, kabhi replace()...
Aur kabhi kabhi clear() karke naye string se append() kare ke padta!

Coding bhi to thoda life jaisan hi baa na?
Aur Guddu ke jaise coder, life ke har function samjhat rahe!

🌞 String Basics in C++ – Jab Sunday ke Subah Guddu Toast Banawat Rahe aur Char Array vs String ke Sawal Aa Gaya!

(Sunday mood wala chill blog – na jyada tension, na jyada confusion!)

🌄 Subah ke Scene – Chai, Bread, aur C++ Strings

Subah ke 9 bajal baa. Guddu kap me chai leke balcony me baithal baa. Sunday baa bhaiya, aaram ke din.

📱 Anmol Ji (Manager):
"Guddu! Char array aur string ke difference samjha do… client confuse baa!"

☕ Guddu:
"Sir, aaj Sunday baa... lekin aapan coding to breathing jaisan baa. Chaliye samjha det bani chill mood me!"

💬 String Ka Matlab Kaa Hoi?

C++ me String ka do major tarika baa:

1. char[] (Character Array)
2. string class (from <string> header)

🧱 Char Array – Old School, Strong but Sensitive

char name[6] = {'G', 'u', 'd', 'd', 'u', '\0'};

• Ek ek character manually daale ke padta.
• Har string ke end me '\0' lagana zaroori baa.
• Memory handling me thoda mahnat baa.

📌 Jaise ki old toaster – bread dal ke time set karo, warna jal jaayi!

🎩 string Class – Modern aur Comfortable

#include <iostream>
#include <string>
using namespace std;

int main() {
    string name = "Guddu";
    cout << "Hello, " << name << "!" << endl;
    return 0;
}

• Simple aur modern.
• Functions milat baa jaise length(), substr(), append().
• Memory management khud handle karela.

☕ Jaise electric toaster – set karo, relax karo, toast tayyar!

⚖️ Char Array vs string – Sunday Morning Comparison

Feature	char[]	string
Syntax	Complex	Simple
Flexibility	Kam	Zyada
Null terminator	Jaruri	Automatic
Function Support	Manual	Built-in

💡 Example: Concatenate Two Strings

Using char array:

char a[10] = "Hi";
char b[10] = "Guddu";
strcat(a, b);
cout << a; // Output: HiGuddu

Using string:

string a = "Hi";
string b = "Guddu";
string c = a + b;
cout << c; // Output: HiGuddu

😅 Char array – jaise bhabhi ke haath se roti belna
😍 string – jaise automatic roti maker!

🚨 Common Mistakes

• char[] me \0 na lagana = crash danger
• cin se input lena to getline use karo

string fullName;
getline(cin, fullName);

🧘 Conclusion

Sunday ho ya Monday, string ke concept clear ho jaayi to coding me maza aa jala.
C++ me char[] purana aur powerful baa, lekin string modern aur relaxed approach baa.
Jaise Sunday ke chai me elaichi ho jaye – waise hi string ka concept samajh jaaye, to din ban jaayi!

📚 Array with Loops in C++ – Jab Guddu Bole: "Repeat Ho Raha Sir!" Aur Anmol Ji Bole: "Loop Lagaa Do Bhaiya, Manual Se Kaam Na Chalega!"

🏢 Office Ke Andar – Kahani Start

Conference room ke whiteboard ke saamne Guddu khada baa. Haath me marker, par dimaag me confusion.

🧑‍💻 Guddu:
"Sir, array bana liye hain int marks[5], sabka number likh diye... par print kaise karen sab?"

👔 Anmol Ji (manager ghoort ke):
"Arey bhai, manual kaam se toh intern bhi resign de dega! Loop lagaa do loop! Repeat karna hai to 'for', 'while', 'do-while' ka istimaal karo!"

💡 Loop Aur Array: Made for Each Other

Array ke andar multiple values ek variable ke naam se store hota. Ab agar sab value print kare ke ba — har index pe jakar kaam kare ke padhi.
Aur iske liye best tool baa loop.

🔁 For Loop ke Saath Array Traversal

#include <iostream>
using namespace std;

int main() {
    int marks[5] = {85, 90, 78, 88, 92};

    for (int i = 0; i < 5; i++) {
        cout << "Student " << i + 1 << " ke marks: " << marks[i] << endl;
    }

    return 0;
}

🗣️ Anmol Ji:
"Guddu, ee 'for' loop ek delivery boy jaisan baa, har ghar (index) pe jakar parcel (value) de de rahal baa!"

⏳ While Loop ke Saath

int i = 0;
while (i < 5) {
    cout << marks[i] << " ";
    i++;
}

🧠 Office Wisdom:
While loop unka ke pasand baa jinke boss har bar poochhe: "Abhi bhi sach hai na?" 😄

🔄 Do-While Loop ke Saath

int j = 0;
do {
    cout << "Marks: " << marks[j] << endl;
    j++;
} while (j < 5);

🤓 Do-while:
Ek aisan manager baa jo pehle kaam karwa le, baad me poochhe: "Condition thik ba na?"

🎭 Real-Life Office Analogy

• Array: Guddu ke inbox me 5 complaint mails.
• For loop: Guddu sab mail read karta ek-ek karke.
• While loop: Jab tak complaint aawat baa, tab tak padhat baa.
• Do-while loop: Ek mail padh liya, ab dekhat baa aur ba ki nai.

📌 Common Mistakes

• ❌ Loop ke range galat set karna
• ❌ Index out of bounds
• ❌ Forgetting i++ (infinite loop danger)

🧹 Anmol Ji: “Loop lagana art baa beta, lekin exit condition naa daale to loop tumhara career loop me daal dega!”

Loop ke bina array bas ek thaila baa — par loop ke saath, u thaila ek systematic inventory list ban jaala.
Office me jaise har employee ke daily report chahiye — waise hi array ke har value par ek nazar loop ke through padhe ke chaahi.

🏢 Kahani Start – Office ke Andar

Manager Anmol Ji ek din kaafi gusse me conference room me ghusela.
Meeting chal raha rahe, aur employee Guddu seedha monitor ke samne thak gail rahe.

👔 Anmol Ji: "Guddu! Ab tu 10 employee ke naam alag variable me rakhat rahalu... ka karat baa tu? Yeh koi ration card list baa?"

🧑‍💻 Guddu (thoda dare-dare):
"Sir, array bana diye rahni, string employee[10];... sabke naam usme daal diye..."

👔 Anmol Ji (table pe thapp thapp):
"Ek column me naam hai, doosra me salary, teesra me department... Sab kaise rakhega tu?
Time aa gail baa 2D Array ka!"

📚 2D Array in C++ – Kaa Hoi Ee?

2D array ek matrix jaise data structure ba — jisme rows aur columns ke form me value rakha jaa sakta.

📖 Syntax:

datatype arrayName[row][column];

Example:

int matrix[3][4]; // 3 rows, 4 columns

---

🧠 Initialization Example

int salary[2][3] = {
    {30000, 35000, 40000},
    {25000, 27000, 29000}
};

👉 Matlab:

• Row 1: 30000, 35000, 40000
• Row 2: 25000, 27000, 29000

---

🔁 Traversing 2D Array with Loops

#include <iostream>
using namespace std;

int main() {
    int data[2][3] = {
        {1, 2, 3},
        {4, 5, 6}
    };

    for(int i = 0; i < 2; i++) {
        for(int j = 0; j < 3; j++) {
            cout << data[i][j] << " ";
        }
        cout << endl;
    }

    return 0;
}

🖥️ Output:

1 2 3  
4 5 6

👔 Manager Anmol Ji (taali bajate):
“Dekha Guddu, jab tu for loop ka jugalbandi karta, tab kaise multi-dimensional data ke tabla baja jaala!”

---

🤹 Real-life Analogy

2D array ek Excel spreadsheet ke jaise ba — har cell me koi na koi value.
employee[row][column] ke logic se tu easily data organize kar sakat ba.

---

📌 Common Use Cases

• Tabular data (salary sheet, student marks)
• Grids (game boards, UI layouts)
• Matrices (for math, physics, AI)

---

🧨 Bonus Tip (from Tech Lead Suman Ji)

• 2D arrays ke data row-major order me store hota.
• Memory allocation fix hota (static array) unless you use dynamic memory (pointers).
