Write a program to read elements of the two matrices of order 3 x 3 and perform the matrix addition.

#include<stdio.h>

#include<conio.h>

void main()

 {

   int a[3][3], b[3][3],s[3][3],i,j;

   clrscr();

   printf("\n Enter elements for matrix A\n");

   for(i=0;i<3;i++)

    {

     for(j=0;j<3;j++)

      {

       printf("\nEnter the number [%d] [%d] ",i,j);

       scanf("%d",&a[i][j]);

      }

    }

   printf("\n Enter the elements for matrix B\n");

   for(i=0;i<3;i++)

    {

     for(j=0;j<3;j++)

      {

       printf("\nEnter the number [%d] [%d] ",i,j);

       scanf("%d",&b[i][j]);

      }

    }

  printf("\n The sum of two matrix is\n");

  for(i=0;i<3;i++)

    {

     for(j=0;j<3;j++)

      {

       s[i][j]=a[i][j]+b[i][j];

      }

    }

   for(i=0;i<3;i++)

    {

     for(j=0;j<3;j++)

      {

       printf("%d\t",s[i][j]);

      }

    printf("\n");

    }

   getch();
