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

If MY_STRUCT is your code, and you are happy using a C++ compiler, you can put the constructor there without wrapping in a class:

struct MY_STRUCT
{
  int n1;
  int n2;
  MY_STRUCT(): n1(0), n2(0) {}
};

I'm not sure about efficiency, but I hate doing tricks when you haven't proved efficiency is needed.
