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

There is no difference in meaning (unless there's more than one name myVar visible, in which case the ordinary version could mean a function-local variable while this->myVar means a member). So yes, it's just a matter of style.
