Write a C program to perform the following:

i. Addition of two matrices

ii. Multiplication of two matrices

Program Code:

#include<stdio.h>

void main()

{

int a[10][10],b[10][10],i,j,m,n,p,q;

printf(" enter row & column of Mat1\n");

scanf("%d%d",&m,&n);

printf(" enter row & column of Mat2\n");

scanf("%d%d",&p,&q);

if(m==p&&n==q)

{

printf(" enter Mat1\n");

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

{ 

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

{ 

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

}

}

printf(" enter Mat2\n");

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

{

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

{ 

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

}

}

printf("\n sum of the matrices\n");

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

{ 

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

{ 

printf("%8d",a[i][j]+b[i][j]);

}

printf("\n");

}

printf("\n difference of the matrices\n");

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

{ 

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

{ 

printf("%8d",a[i][j]-b[i][j]);

}

printf("\n");

}

}

else

printf("\n operations not possible...");
