【NO.3】 c program to caculate and display sum of two matrix

source code:

#include "stdafx.h"

/* display sum of two matrix*/

int _tmain(int argc, _TCHAR* argv[])

{

 int a[3][3], b[3][3], c[3][3], i, j;

 i = j = 0;

 printf("input elements into the first matrix a[3][3]\n");

 for (i = 0; i < 3; i++)

 {

  for(j = 0; j < 3; j++)

  {

   scanf_s("%d", &a[i][j]);

  }

 }

 printf("input elements into the first matrix b[3][3]\n");

 for (i = 0; i < 3; i++)

 {

  for(j = 0; j < 3; j++)

  {

   scanf_s("%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("the sum of the two matrix is below:\n");

 for (i = 0; i < 3; i++)

 { 
  for(j=0;j<3;j++) 
  {
   printf("%d ",c[i][j]);   
  }
  printf("\n");
