To add two matrix A and B.

Program:
 #include<stdio.h>
#include<conio.h>
void main()
{
int i,j,m,n,p,q;
int a[10][10], b[10][10], c[10][10];
clrscr();
printf("\nEnter no of rows and column of matrixA:");
scanf("%d%d",&m,&n);
printf("\nEnter no of rows and column of matrixB:");
scanf("%d%d",&p,&q);
if(m!=p && n!=q)
{
printf("\n Matrix cannot be added.");
exit(0);
}
printf("\n Matrix can be added");
printf("\n Enter elements of matrix A:");
for(i=0;i<m;i++)
for(j=0;j<n;j++)
scanf("%d",&a[i][j]);
printf("\n Enter elements of matrix B:");
for(i=0;i<p;i++)
for(j=0;j<q;j++)
scanf("%d",&b[i][j]);
for(i=0;i<m;i++)
for(j=0;j<n;j++)
c[i][j]=a[i][j]+b[i][j];
printf("\n Display matrix A:\n");
