When should I make explicit use of the `this` pointer?

Question

When should I explicitly write this->member in a method of a class?

Answer 1

You need to use this to disambiguate between a parameters/local variables and member variables.

class Foo
{
protected:
  int myX;

public:
  Foo(int myX)
  {
    this->myX = myX; 
  }
};
