C Program to Add Two Matrix

      Add two matrix in C programs is given by the user, And also given the range by the users. It is a simple methods of additions of two matrix.


C programming code

#include<stdio.h>
#include<conio.h>

void main()
{
   int a[3][3], b[3][3], sum[3][3], i, j, n;
   clrscr();
   printf("\n Enter the number of same rows and columns of matrix ");
   scanf("%d",&n);
   printf("\n Enter the elements of first matrix\n");
   for ( i = 0 ; i < n ; i++ )
     for ( j = 0 ; j < n ; j++ )
        scanf("%d",&a[i][j]);
   printf("\n Enter the elements of second matrix\n");
   for ( i = 0 ; i < n ; i++ )
     for ( j = 0 ; j < n ; j++ )
           scanf("%d",&b[i][j]);

   for ( i = 0 ; i < n ; i++ )
      for ( j = 0 ; j < n ; j++ )
         sum[i][j] = a[i][j]+ b[i][j];

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

   for ( i = 0 ; i < n ; i++ )
   {
      for ( j = 0 ; j < n ; j++ )
         printf("%5d",sum[i][i]);
      printf("\n");
   }
   getch();
}


Output:-
