cpp 2d array define code example
Example 1: 2d array c++
int a[2][3]= {
{1, 2, 3},
{4, 5, 6}
};
cout << a[1][1]; // Output is 5
Example 2: 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;
}
