Sample C Program To Add Two Matrices.

#include <stdio.h>
#include <conio.h>
int main()
{

int m, n, i, j;
int first[10][10], second[10][10], sum[10][10];

printf(" Enter the number of rows and columns of matrix ");
scanf(" %d %d ", &m, &n);

printf(" Enter the elements of first matrix\n ");
for ( i = 0 ; i < m ; i++ )
      for ( j = 0 ; j < n ; j++ )
          scanf(" %d ", &first[i][j] );

printf("Enter the elements of second matrix\n");
for ( i = 0 ; i < m ; i++ )
      for ( j = 0 ; j < n ; j++ )
          scanf(" %d ", &second[i][j] );

for ( i = 0 ; i < m ; i++ )
      for ( j = 0 ; j < n ; j++ )
           sum[i][j] = first[i][j] + second[i][j];

printf(" Sum of entered matrices:-\n ");
for ( i = 0 ; i < m ; i++ )
    {
       for ( j = 0 ; j < n ; j++ )
             printf(" %d\t ", sum[i][j] );
       printf(" \n ");
    }
getch();
return 0;

}
