Parallel assignment in C++

Question

Is there any way of doing parallel assignment in C++? Currently, the below compiles (with warnings)

#include  

int main() { 
  int a = 4;
           


        

Answer 1

Or Lua...
There are tricks with C/C++, like using xor or operations, but with risk of overflow and such. Just do it the painful way, with three assignments. Not a big deal.
