2D Arrays in C++ – Jab Manager Bola: "Ek Row Se Kaam Na Chale, Column Bhi Chahiye Bhaiya!"

🏢 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).

🎯 Conclusion

2D array ek powerful concept baa C++ me, jisse tu complex data (like employee record) easily manage kar sakat ba. Office me jaise sabko ek table chahiye rehta — waise program me 2D array waise table de jaala.
