I have a class. There is a function and a variable.
class myClass
   int num;
   int Calc(int x);

int myClass::Calc(int x)
   int num = 12536; //constant
   return num /*First One (Global)*/ + num /*2nd One (1 inside the function*/ + x;

Now, How Can I use both variables(num's) inside Calc Function ? I think above function is not corrent.

Try this.num for the "gobal"

this is very bad programming. Avoid reusing names like this.
There is coding conventions to be followed:
int _num; for member variables
int lnum; for local variables if you want to emphesize that they are local.
variable name hiding is what you do here, and is not a good idea.

To referance your class member.

Actualy the best solution would be to change the names so as to remove any ambiguity.

Will also work though.
