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.

can say it a reference i.e we can put any other variable
instead of r.
