Ошибка идентификатор getline не определен

For your first error, I think that the problem is in this declaration:

 const float APRICE = 6.00,
       float CPRICE = 3.00;

In C++, to declare multiple constants in a line, you don’t repeat the name of the type. Instead, just write

 const float APRICE = 6.00,
             CPRICE = 3.00;

This should also fix your last error, which I believe is caused by the compiler getting confused that CPRICE is a constant because of the error in your declaration.

For the second error, to use getline, you need to

#include <string>

not just

#include <cstring>

Since the getline function is in <string> (the new C++ string header) and not <cstring> (the old-style C string header).

That said, I think you’ll still get errors from this, because movieName is declared as an int. Try defining it as a std::string instead. You might also want to declare your other variables as floats, since they’re storing real numbers. More generally, I would suggest defining your variables as you need them, rather than all up at the top.

Hope this helps!

I’m using VS windows, my friend who coded this was using another program, and it worked, but not on mine… I’m going crazy!
