📦 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!
