C++

///////////////////////////////////////////////////

This is the code i have so far, it is

finished but giving me errors!

  1. Error (active) E2140 expression must have integral or unscoped enum type...LINE 82
  2. Error (active) E0299 cannot determine which instance of function template "std::endl" is intended... LINE 82
