& operator

Question

Hey friends
I know if we have a code like this:
int *a=&b;
The value of a will be the address of b and & operator returns the address of a variable but what will be the operator performance in this code:
int b;
int &a=b;

Answer 1

GHOST mHBr

This concept is introduced in C++, here a is called reference variable .
A reference variable provides an alternative name for previously defined variable

In your code -
int b;
int &a = b;

a is a reference variable which contain reference of b.
{In short, a is just another name of b}
