 #include <iostream>
 
 int main()
 {
     int a, b;

     ++a++;
  // The line above should give you a compiler error!  Comment it out.
  // It doesn't really make sense to try to increment before
  // and then after evaluation, does it? If you want to add 2
  // you can do so with a += 2;
  // or you can do something like:
     b = ++a;
     a++;

     std::cout << "a is " << a << std::endl;
     std::cout << "b is " << b << std::endl;

     return 0;
