How can I make a struct array [30]?

Question

Hello I'm a bit confused about struct arrays...

How can I make an array with this struct:

struct m_StudentData
{
    char Sex, Class [10];
    char Phone [15];
    char Name, Surname, Nationality [30];
    char Rooms, Subjects, Mail [64];
    CString Information, Address;
    CDateTimeCtrl Birthday;
}

Be careful, m_StudentData is a type name, I have met the naming with the prefix 'm_' to members (like `Sex` or `Address`) — sop, Sep 24 '14 at 06:59

simple, just use the struct as type

struct m_StudentData
{
    char Sex, Class [10];
    char Phone [15];
    char Name, Surname, Nationality [30];
    char Rooms, Subjects, Mail [64];
    CString Information, Address;
    CDateTimeCtrl Birthday;
};

m_StudentData arr[30];

Add semi-colon at the end of your struct declaration. Also, don't use `memset` with this class, as it is not POD. – Ajay Sep 24 '14 at 07:01
You need to define the struct before main, or declare it before main, or in a header that you include. (and, as mentioned, you have forgotten the `;` after the struct's last `}`) – sop Sep 24 '14 at 07:01
Add semicolon at the end, edited my earlier ans – Dr. Debasish Jana Sep 24 '14 at 07:02
@DebasishJana Let's wait for the next question in a comment _But now I get an error in (something totally unrelated) ..._ ;) – πάντα ῥεῖ Sep 24 '14 at 07:06
hahahah yeah I got some other errors but I think its because I made the struct array in an additional header file. So I think I have to declare it in another file? – Fabian Wüthrich Sep 24 '14 at 07:07
declare the struct in header file and the array (if global) must be in some implementation file (.c, or .cpp whatever you have) – Dr. Debasish Jana Sep 24 '14 at 07:09
