    declare and initialize struct members

    hello,

    thats maybe a stupid question but i got stuck on it. is there any way to not only declare but initialize array/pointer members in a struct or union?

    No and yes.

    You can't initialize ANYTHING in a struct or union declaration.

    You can initialize into a variable declared of a struct or union type.

    For example:
    Code:
    struct something {
        int x;
        int *ptr;
    };
    
    int someint;
    
    struct something somevar = { 0, &someint };

    Compilers can produce warnings - make the compiler programmers happy: Use them!

    You can also use ZeroMemory or memset to 0 out everything in a struct. This is always recommended if you're not initializing the struct as outlined above (since some member may have junk data otherwise).
