c program to add two matrix

This c program add two matrices i.e. compute the sum of two matrices and then print it. Firstly user will be asked to enter the order of matrix ( number of rows and columns ) and then two matrices. For example if the user entered order as 2, 2 i.e. two rows and two columns and matrices as

#include<stdio.h>

#include<conio.h>

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 ");

   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");

   }

   getch();

   return 0;

}
