Structs...

[Virtual24]

Two questions:

1) Do structs need constructors/destructors and if not, can they have them.

2) Can you declare anything in a struct as private or protected, or does everything have to be public ( by default ).

If anyone knows the answers to these questions it would help out a lot. ~Thanx~

structs ARE classes, except that everything is BY DEFAULT public instead of private. Other then that, there is no difference, so, yes, they CAN, but dont HAVE to have constructors/destrcutors, and they CAN have private or protected sections.

Haha, thanx for helping me... Sorry if it sounded like i was yellng with the bold type and all. :-)

Yes, while you MIGHT have SOUNDED like you were YELLING, I got the picture =).

But if you use structs this way, you might just as well use a class, which makes the code more readable.

True, CB. THe most I will add onto a struct is a constructor or destructor, but only then when It is something like a linked list node (zero out the pointers). Anything more is a class.

In my little book it here... ehh it says

A structure is a class declared with the class-key struct.

And further on it basically says that structs were put in C++, so that you could use old C code that say took a struct as a parameter.

Exactly. The struct keyword is not necessary in C++. It is there for backwards compatibility mainly.

The struct keyword in C++ shouldn't be used differently than in C. This means no methods, no access specifiers, no derivation. Maybe a constructor or destructor. But only if it really makes sense.
