Write a Program to add any two 3x3 matrices.

Source Code :

#include<stdio.h>

void main()

{

      int a[3][3],b[3][3],c[3][3],i,j;

      clrscr();

      printf("\nEnter Matrix A : ");

      for(i=0;i<3;i++)

            for(j=0;j<3;j++)

                  scanf("%d",&a[i][j]);

      printf("\nEnter Matrix B : ");

      for(i=0;i<3;i++)

            for(j=0;j<3;j++)

                  scanf("%d",&b[i][j]);

      for(i=0;i<3;i++)

            for(j=0;j<3;j++)

                  c[i][j]=a[i][j]+b[i][j];

      printf("\nAfter Addition : \n");

      for(i=0;i<3;i++)

      {

            for(j=0;j<3;j++)

                  printf("%d\t",c[i][j]);

            printf("\n");

      }

      getch();

}

Output :

Enter Matrix A : 5 6 9 8 7 4 1 2 3

Enter Matrix B : 2 5 6 9 8 4 3 1 7

After Addition :

7     11    15

17    15    8

4     3     10
