Question

Suppose I have a class like:

Class MyClass 
{ 
  int myVar1;
  int myVar2;

  void myMethod(); 
}

is there any difference in the two value assignments below ?

void MyClass::myMethod()
{
   //VARIABLE ASSIGNMENT
   myVar1 = 99;

   //USING POINTER TO CLASS
   this->myVar2 = 99;
}

What’s the use of the

this->

pointer in variables’ assignment (except other cases when eg. passing the class via a function etc.) ?

Answer 1

It’s the same thing, unless you happen to have two variables with the same name in the scope. In that case you can differentiate using this->.
