Question

In C i can test the value of an enum using if/else statement. For example:

enum Sport {Soccer, Basket};


Sport theSport = Basket;

if(theSport == Soccer)
{
   // Do something knowing that it is Soccer
}
else if(theSport == Basket)
{
   // Do something knowing that it is Basket
}

Is there another way to do this work with C++?

Yes, instead of using if-else statement, you can use virtual functions as part of interfaces.

I make you an example:

class Sport
{
public:
    virtual void ParseSport() = 0;
};

class Soccer : public Sport
{
public: 
    void ParseSport();
}

class Basket : public Sport
{
public:
    void ParseSport();
}

And after use your object in this way:

int main ()
{
    Sport *sport_ptr = new Basket();

    // This will invoke the Basket method (based on the object type..)
    sport_ptr->ParseSport();
}

This is thanks to the fact that C++ adds object oriented features.
