Re: Overloading Of ( ) is possible

Are you thinking about using the () as the conversion operator or talking about overloading the () operator to do something like addition or concatenation or some other theoretical possibility?

Re: Overloading Of ( ) is possible

When you overload the () operator, it's used as if it were a function call operator and nothing more:

C++ Syntax (Toggle Plain Text)
#include <iostream>
 
struct foo {
    void operator()()
    {
        std::cout<<"FOO!\n";
    }
};
 
int main()
{
    foo bar;
 
    bar();
}
#include <iostream>

struct foo {
    void operator()()
    {
        std::cout<<"FOO!\n";
    }
};

int main()
{
    foo bar;

    bar();
}

If that's not what you want, you're SOL.

Re: Overloading Of ( ) is possible

It sounds disturbingly like you're looking for a problem to fit the solution you recently learned. That's silly.
