When using an IDE, what must you do to use a class that's stored in a library? Select one: a. Nothing. Classes in libraries are automatically available. b. Code an import statement for the class. c. Add the library to your project. d. Both b and c.

Both B and C

Explanation:

In order to use methods from another class (library) in your code, the class library will have to be added or imported into your code.

C++ uses the key word #include

C# Uses the keyword using
