Question

I have template method and i would like the template method use a specific method from a class to do the operation. Is it possible ?

template<typename T>
int minus(T t1,T t2){
return t1-t2;
}

And in my apple object class i have a method called getPrice()
How can i combine both.

Is this correct ?

template<typename T>
int minus(T t1,T t2){
return t1.getPrice()-t2.getPrice();
}

Answer 1

For this you probably want an ordinary function for your type:

template <class T>
int minus(T t1, T t2) {
    return t1 - t2;
}

int minus(const apple& t1, const apple& t2) {
    return t1.getPrice() - t2.getPrice();
}
