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.

Answer / kumar sourav
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.

Coin Problem You are given 9 gold coins that look identical. One is counterfeit and weighs a bit greater than the others, but the difference is very small that only a balance scale can tell it from the real one. You have a balance scale that costs 25 USD per weighing. Give an algorithm that finds the counterfeit coin with as little weighting as possible. Of primary importance is that your algorithm is correct; of secondary importance is that your algorithm truly uses the minimum number of weightings possible. HINT: THE BEST ALGORITHM USES ONLY 2 WEIGHINGS!!!
