It is not seen what is the initial value of rat and what is the condition of the loop.

¿what?

By the way, I think that rat15=rat15++; is undefined

I think it is fine because in all cases, the assignment is sequenced after the value computation of the right and left operands. That would mean rat15=rat15++; is equivalent to rat15;.

#include <iostream>
int main(){
   int n=42;
   n = n++;
   std::cout << n << '\n';
}

Specifically, "value computation" is not all that rat15++ is doing.
