Question

So, I am looking to make my code cleaner. Here is what I have:

obj.hpp

class obj {
    obj();

    int return0();
};

obj.cpp

using namespace obj; //illegal!!
obj() { }

int return0()
{
    return 0;
}

Basically, I think that writing obj::return0()... is a bit redundant. This becomes trickier when I have sub-classes, where I do things like obj::child::child2::return0()...

Any ideas?

using namespace x lets you call functions in x, not define them.

As a comment pointed out, you can inline the function in the header file if it’s short.

obj.hpp

class obj {
    obj(){}
    int return0(){return 0;}
}
