do you have to re-type "virtual" in derived classes
Do you have to re-type the "virtual" keyword in a derived class for the overridden methods (where the methods are virtual in the base class):
eg:
class base {
virtual void foo(){/*do something*/};
}
class derived : public base {
/*type "virtual" here? */ void foo(){/*do something else */};
}
eg:
class base {
virtual void foo(){/*do something*/};
}
class derived : public base {
/*type "virtual" here? */ void foo(){/*do something else */};
}
No, you don't need it.
( I Personally think that repeating it is good as you can know which methods are virtual without having to look to the base class )

I agree with Bazzy on re-typing it. It is a convenient reminder or a nice indicator for maintainers to pick up on.
