Two-Dimensional Array Manipulation in C++

This simple C++ program shows how to manipulate a two dimensional array. In this case it will traverse through the array and print its contents.

#include <iostream>
using namespace std;
#define m 3
#define n 3
int main(void)
{
    int i, j;
    int x[m][n] = {{10, 25, 33}, {21, 32, 43}, {20, 42, 51}};
    cout << "\n3x3 arrays' subscripts and\n";
    cout << "their respective elements\n";
    cout << "--------------------------\n";
    // outer for loop, reading the row by row...
    for (i = 0; i < m; i++)
        // inner loop, for every row, read every column by column...
        for (j = 0; j < n; j++)
            cout << "[" << i << "]"
                 << "[" << j << "]"
                 << "=" << x[i][j] << "\n";
    return 0;
}
