Write a C++ program that uses a function smallo() (that is passed two int argument by value) to receive reference of the smaller value. Then using this reference the smaller value is set to 0. Write a main() function also to exercise this function.

/* This is a example of return by reference */ 

#include<iostream.h>

#include<conio.h>

int &smallo(int a, int b)
{
if(a>b)
  return a;
else
  return b;
}


void main()
{
int a, b;
cout<< "\n Enter two numbers :";
cin >> a >> b;

cout<< "\n The original values :" << a << "  and " << b;

smallo(a, b) = 0;

cout<< "\n The changed values :" << a << " and " << b;



getch();
