Program to calculate sum of two matrices in C.

Code is here..

//AIM: TO PERFORM THE ADDITION OF TWO MATRIX

#include<stdio.h>

#define m 3

#define n 3

void add(int[][n],int[][n]);

void main()

{

int a[m][n],b[m][n],i,j;

printf("enter the elements of a 3*3 matrix:\n");

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

{ for(j=0;j<n;j++)

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

}

printf("enter the elements of another 3*3 matrix:\n");

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

{ for(j=0;j<n;j++)

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

}

printf("given matrix are:\n");

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

{ for(j=0;j<n;j++)

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

printf("\n");

}

printf("AND\n");

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

{ for(j=0;j<n;j++)

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

printf("\n");

}

add(a,b);

}

void add(int a[m][n],int b[m][n])

{

int c[m][n],i,j;

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

{ for(j=0;j<n;j++)

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

}

printf("addition is:\n");

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

{ for(j=0;j<n;j++)

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

printf("\n");

}

}
