Write a C program to add two matrix.

#include <stdio.h>

void main()

{

   int m, n, c, d, first[10][10], second[10][10], sum[10][10];

   printf("Enter the number of rows and columns of matrix\n");

   scanf("%d%d", &m, &n);

   printf("Enter the elements of first matrix\n");

   for ( c = 0 ; c < m ; c++ )

      for ( d = 0 ; d < n ; d++ )

         scanf("%d", &first[c][d]);

   printf("Enter the elements of second matrix\n");

   for ( c = 0 ; c < m ; c++ )

      for ( d = 0 ; d < n ; d++ )

            scanf("%d", &second[c][d]);

   for ( c = 0 ; c < m ; c++ )

      for ( d = 0 ; d < n ; d++ )

         sum[c][d] = first[c][d] + second[c][d];

   printf("Sum of entered matrices:-\n");

   for ( c = 0 ; c < m ; c++ )

   {

      for ( d = 0 ; d < n ; d++ )

         printf("%d\t", sum[c][d]);

      printf("\n");

   }
