Is this C++ structure initialization trick safe?

Question

Instead of having to remember to initialize a simple \'C\' structure, I might derive from it and zero it in the constructor like this:

struct MY_STRUCT
{
            


        

Answer 1

This would make me feel much safer as it should work even if there is a vtable (or the compiler will scream).

memset(static_cast(this), 0, sizeof(MY_STRUCT));

I'm sure your solution will work, but I doubt there are any guarantees to be made when mixing memset and classes.
