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.

Answer / shiv

according to me int &r is declaration , and int& r is
reference .

hello friends, given an expression we have to remove the unwanted brackets in that expression. Eg : (a+b) ---> a+b (a+b)*(c)-----> (a+b)*c. Please mail me if you know the logic. My mail id is : saravana6m@gmail.com. Thank you in advance :-)
