Pointer References In C++

If we declare any type of variable then we have to use address operator at  that time it  is called variable reference.

If reference variable is integer type then variable address can store, and reference variable memory allocation is  in heap.

In normal variable memory allocation is in static, its means reference variable use to copy, so that kind of variable is known as  pointer reference.

Example:

int  a;

a=30;

int &b=a;

 

Program:

#include<iostream.h>

#incldue<conio.h>

void main()

{

int  num;

int &num1=num;

cout<<”input a value”;

cin>>num;

cout<<”num=”<<num;

cout<<”num1=”<<num1;

getch();

}

 

Output:

input a value 2

num=2, num1=2
