Two-Dimensional Array Manipulation in C++
By: Ignatius in C++ Tutorials on 2012-03-16
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; }
