Hello. I'd like to be able to do something like this:
I have a struct foo (int x,y,z) and a void* bar=&foo;
So bar holds the adress of foo. I know that at the beginning of the
struct lies the first member. so why can't I just say *bar=55 or
something?
I'd like to be able to access any member of a struct using a pointer.
Like, if I want to access the second member, I add 4(or whatever) to the
pointer and write the value to that adress. How could I do that? HELP!!
TIA,
