const and virtual usage

[john smith]

Hi, say I have a class like so:

class A {
public:
virtual void foo();
void bar() const;
};

so when I actually define foo() and bar(), do I have to re-type the virtual
and const modifiers respectively? Is it more a matter of style?

So is this necessary?:
virtual void foo() {
//do something
}
void bar() const {
// do something
}

thanks in advance.

NO! Exactly the opposite!

//do something

It is not necessary. In fact, it is illegal. You cannot put the virtual type
modifier here, only in the class definition. virtual only goes there, not in
the definition.

void bar() const {
// do something
}
This is how you must do it. const MUST be in the definition, unlike virtual.
thanks in advance.
