How to call function from class to main?

Question

I need conj for complex number.

For example complex number X.

I wrote this code, but i dont know how to call it in main.

Kompleks operator ~() const {
    return Kompleks(Re() , -Im());
}

Answer 1

You can call it like

int main() {
    Kompleks X;
    Kompleks conj = ~X;
}

Answer 2

You have just implemented the Complement Operator of the class "Kompleks" ( documentation here ). In your main, if x is a Kompleks object, writing "~x" will yield the conjugate of x. For example :

Kompleks x(1, 2);
Kompleks y(0, 0);

y = ~x;

after this code, y will contain the conjugate of x.
