Write a c program to add two matrices using functions?

Answer 1

#include<stdio.h>

#include<conio.h>

#include<math.h>

void main()

{

int a[4][4],b[4][4],c[4][4],i,j;

printf("enter the elements of matrix a");

for(i=0;i<=3;i++)

for(j=0;j<=3;j++)

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

printf("the first matrix is");

for(i=0;i<=3;i++)

{

printf("\n");

for(j=0;j<=3;j++)

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

}

printf("Enter the elements of second matrix");

for(i=0;i<=3;i++)

for(j=0;j<=3;j++)

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

printf("the second matrix is");

for(i=0;i<=3;i++)

{

printf("\n");

for(j=0;j<=3;j++)

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

}

for(i=0;i<=4;i++)
