    saving a class... binary style

    if i was to output like this

    PHP Code:
    class cRect{
         public:
             
    cRect(int xint yint wint h);
             
    int x,y,w,h;
    };

    class 
    sRect//or just struct sRect
          
    public:
             
    int x,y,w,h;
    };
         
    ....

    cRect cr;
    sRect sr;

    ....

    ofstream binout("file.dat",ios::out|ios::binary);
    binout.write( (char*)&sRectsizeof(sRect));
    binout.write( (char*)&cRectsizeof(cRect));

    .... 
    would these both do the same thing?? basically what i'm asking is if having methods affects the size of a class for these purposes.

    if this worked couldn't i use sRect and cRect interchangably in I/O?

    thanks in advance

    methods should absolutely add NO size to the class,
    if they do get a nw compiler.

    if thats what your asking.

    theoritically yes.
