c++ code to write 2d array
#include <iostream>
using namespace std;
int main(){
int n,m;
int a[n][m];
cin >> n >>m;
for ( int i=0; i<n; i++){
for (int j=0; j<m; j++){
cin >> a[i][j];
}
}
for ( int x=0; x<n; x++){
for (int y=0; y<m; y++){
cout << "a[" << x << "][" << y << "]: ";
cout << a[x][y] << endl;
}
}
return 0;
}c fill 2d array
// Either
int disp[2][4] = {
{10, 11, 12, 13},
{14, 15, 16, 17}
};
// Or
int disp[2][4] = { 10, 11, 12, 13, 14, 15, 16, 17};
// OR
int i, j;
for (i = 0; i < HEIGHT; i++) { // iterate through rows
for (j = 0; j < WIDTH; j++) { // iterate through columns
disp[i][j] = disp[i][j];
}
