Addition 3X3 Matrix using function

/*program of addition of two given 3X3 matrix through function*/
#include<stdio.h>
#include<conio.h>
void show_matrix(int mat[3][3]);
void add_matrix(int matA[3][3], int matB[3][3], int matSum[3][3]);
int main()
{
 int x[3][3] = { {1,2,3}, {4,5,6}, {7,8,9} };
 int y[3][3] = { {1,4,7}, {2,5,8}, {4,1,2} };
 int z[3][3];
 add_matrix(x,y,z);
 printf("\nFirst matrix is :\n");
 show_matrix(x);
 printf("\nSecond matrix is :\n");
 show_matrix(y);
 printf("\nNew addition matrix is :\n");
 show_matrix(z);
 getch();
 return 0;
}


void add_matrix(int matA[3][3], int matB[3][3], int matSum[3][3])
{
  int r,c;
  for(r=0; r<3; r++)
  {
    for(c=0; c<3; c++)
        matSum[r][c]=matA[r][c]+matB[r][c];
  }
}


void show_matrix(int mat[3][3])
{
  int r,c;
  for(r=0; r<3; r++)
  {
    for(c=0; c<3; c++)
        printf(" %d",mat[r][c]);
    printf("\n");
  }
}


             Output of above program : 

First matrix is :
1 2 3
4 5 6
7 8 9


Second matrix is :
1 4 7
2 5 8
4 1 2


New addition matrix is :
2  6  10
6  10 14
11 9  11
