Is there any overhead using this-> for accessing a member?

Question

When accessing a member of some class, I can use e.g.:

this->myVar = 10 

or I can just write:

myVar = 10

Answer 1

I sometimes uses explicit this-> in setters, since they allow me to use the same name for the parameter names as the instance fields:

class MyClass 
{
    int foo;
    void setFoo(int foo) 
    {
        this->foo = foo;
    }
}

however, in constructors, I usually use initialization list, which does not require an explicit this->

class MyClass 
{
    int foo;
    MyClass(int foo) : 
        foo(foo) 
    { 
    }
}
