AppCUI VS ltsim

Been there done that and in hindsight: while it was a good way to learn some Windows quirks/internals, I now really feel that time would have been better spent learning how to use an existing library (say, https://gdt050579.github.io/AppCUI/, just to name something).

You could try https://github.com/gdt050579/AppCUI . It's still in development, but we have a lot of examples that work that you can try. If you want you can message me for help :)

in modern C++ you should avoid raw pointers (or let's say it differently: you have to have a valid reason to use them) and use a smart version provided by the std library, usually std::unique_ptr is what you're searching for. Also if I'm not wrong, the memory assigned to "win" is never released because the dtor body is empty (that's the perfect example that explains why you want to use a smart pointer).If after switching from raw pointer to a smart pointer you still need to write explicitly a destructor, you should be conform to the rule of 5 (provide copy ctor and assignment, and move ctor and assignment as well).
