3 - What about virtual destructor ? is Garbage collector work like in C# in those cases ?

Please, anyone out there, can you explain clearly how to deal with Functions. I need more information on;
-create function,
-call function
-anything about functions and their applications.

Declare them :  (); 
Define them  :  () { }
& 
Call them    :  x = ();

int number = 5;
number = number + 1;
number = number * 7;
number = number / 2;

int ProcessNumber(int number)
{
  number = number + 1;
  number = number * 7;
  number = number / 2;
}

num1 = ProcessNumber(5);
num2 = ProcessNumber(34);
num3 = ProcessNumber(-9);
