It won't run

What errors do you get?

@shadowCODE

error C3867: 'std::basic_istream<char,std::char_traits<char>>::ignore': function call missing argument list; use '&std::basic_istream<char,std::char_traits<char>>::ignore' to create a pointer to member

it points to the cin.ignore on lines: 30, 45,48,56,63
shadowCODE (680)
cin.ignore(256,'\n');

Bro you are the best. Can u explain me why this works and regular cin.ignore wouldn't work, cause the way my teacher taught me is just to use regular cin.ignore.

"Regular cin.ignore" does work, but you have to actually call the function:

cin.ignore();

Besides, regular cin.ignore is not cin.ignore. it is cin.ignore().
