C++ Program to find MULTIPLICATION OF MATRICES

#include<iostream.h>

#include<conio.h>

void main()
{
int a[5][5],b[5][5],c[5][5],i,j,k,sum=0,m,n,o,p;
clrscr();
printf("\nEnter the row and column of first matrix");
scanf("%d %d",&m,&n);
printf("\nEnter the row and column of second matrix");
scanf("%d %d",&o,&p);
if(n!=o)
{
printf("Matrix mutiplication is not possible");
printf("\nColumn of first matrix must be same as row of second matrix");
}
else
{
printf("\nEnter the First matrix->");
for(i=0;i<m;i++)
for(j=0;j<n;j++)
scanf("%d",&a[i][j]);
printf("\nEnter the Second matrix->");
for(i=0;i<o;i++)
for(j=0;j<p;j++)
scanf("%d",&b[i][j]);
