Write a program to find maximum of 2 Nos. using friend function.

#include<iostream.h>
#include<conio.h>
template <class mytype>
mytype maxi(mytype x,mytype y)
{
   return(x>y?x:y);
}
void main()
{
    int i,j;
    long m,n;
    clrscr();
    cout<<"\nEnter 2 integers:";
    cin>>i>>j;
    cout<<"\nEnter 2 long integer:";
    cin>>m>>n;
    cout<<"\nMaximum of two integers:"<<maxi(i,j)<<endl;
    cout<<"\nMaximum of two long values :"<<maxi(m,n)<<endl;
    cout<<"\nMaximum of char x and a:"<<maxi('X','a')<<endl;
    getch();
