OOP - Is it a good way to override class member variable type

Question

I have a pre-defined struct (unchangable)

struct ACCOUNT
{
    char IDAccount[MAX_IDACCOUNT_LENGTH];
    char fullName[MAX_FULLNAME_LENGTH];
    int type;
};

Now, I want to override the type of the type member variable. Is this a right way doing it?

enum ACCOUNT_TYPE {ACCOUNT_TYPE_SV, ACCOUNT_TYPE_CB, ACCOUNT_TYPE_OT};

struct Account : virtual ACCOUNT {
    ACCOUNT_TYPE type;
};

All you're doing is shadowing the base classes member. That's not _'overriding'_ ... — πάντα ῥεῖ, Apr 08 '14 at 15:53
No. You cannot override types of member variables. There's no good way, no bad way and no any other way. — n. m. could be an AI, Apr 08 '14 at 15:58

In your second definition you are just shadowing ACCOUNT::type. There's no way for you to modify the type of ACCOUNT::type (unless you modify the actual definition of ACCOUNT, which you defined as "unchangeable").

See this question if you want to cast the int to an enum instead.
