3-Dimensional Array

Arrangement of data elements or numbers in the form of rows and columns.

$$\begin{bmatrix} 00 & 01 & 02 \\ 10 & 11 & 12 \\ 20 & 21 & 23 \end{bmatrix}$$

// program that demonstrates how an array works
#include <iostream>
using namespace std;

int main() {
    int marks[3][3];

    for(int i = 0; i < 3; i++) {
        for(int j = 0; j < 3; j++) {
            marks[i][j] = (i + 1) * (j + 1);
            cout << marks[i][j] << "\t";
        }
