Answer / nakubu

There is no difference; C++ is pretty much whitespace
agnostic. What depends is its use:

int function(int &r)
{
...
}

is a function declaration that accepts an integer pointer as
a parameter, and:

int a = 7;
int &r = a;

will make a reference to an integer.

The spacing around the & makes no difference.

according 2 me int &r is a declaration in which address of
r is of integer datatype whereas int& r is an alias or we
can say it a reference i.e we can put any other variable
instead of r.

Answer / shiv

reference .
