Here I am  posting programs which are in our lab list. If you find any mistakes or  you want to suggest any thing  kindly post them in comment section.

NOTE: All these programs work only in turbo compilers

#include<iostream.h>
#include<conio.h>
class max
{
public:
void max1(int ,int );     //pass by value
void max2(int *,int *);   //pass by address
void max3(int &,int &);   //pass by reference
int & max4(int &,int &);  //return by reference
};
void max::max1(int a ,int b)
{
if(a>b)
cout<<a<<" is greater than "<<b;
else
cout<<b<<" is greater than "<<a;
}
void max::max2(int *a,int *b)
{
if(*a>*b)
cout<<*a<<" is greater than "<<*b;
else
cout<<*b<<" is greater than "<<*a;
}
void max::max3(int &a,int &b)
{
if(a>b)
cout<<a<<" is greater than "<<b;
else
cout<<b<<" is greater than "<<a;
}
int &max :: max4(int &a,int &b)
{
if(a>b)
return a;
else
return b;
}
/*********MAIN FUNCTION**********/

{
clrscr();
