print matrix in c++ code example
Example 1: print matrix c++
#include <iostream>
using namespace std;
int matrix[3][3];
int main()
{
// asigning values, I suppose this is done allready.
for(int x=0;x<3;x++)
{
for(int y=0;y<3;y++)
{
matrix[x][y]=1;
}
}
// showing the matrix on the screen
for(int x=0;x<3;x++) // loop 3 times for three lines
{
for(int y=0;y<3;y++) // loop for the three elements on the line
{
cout<<matrix[x][y]; // display the current element out of the array
}
cout<<endl; // when the inner loop is done, go to a new line
}
return 0; // return 0 to the OS.
}
Example 2: how to print a 2d array in c++
for (int i = 0; i < m; i++)
{
for (int j = 0; j < n; j++)
{
cout << arr[i][j] << " ";
}
// Newline for new row
cout << endl;
}
