[Solved] Is a++ = b++ = 0 safe

Question

In C and C++ you need to consider the possibility that a == b, which would certainly render it unsafe. And in C++ you also need to exclude the possibility that a and b refer to the same name, i.e. that at least one is a reference. But excluding that, and assuming *a and *b are themselves valid, yes, each object is evaluated and assigned once.
