C++ Class or Struct compatiblity with C struct

Question

Is it possible to write a C++ class or struct that is fully compatible with C struct. From compatibility I mean size of the object and memory locations of the variables. I k

Answer 1

As long as your class doesn't exhibit some advanced traits of its kind, like growing something virtual, it should be pretty much the same struct.

Besides, you can change Class (which is invalid due to capitalization, anyway) to struct without doing any harm. Except for the members will turn public (they are private now).

But now that I think of your talking about type conversion… There's no way you can turn float into long representing the same value or vice versa by casting pointer type. I hope you only want it these pointers for the sake of moving stuff around.
