Unit 4: Advanced Concepts
This unit begins with a review of function and class templates, which make programs adaptable. We will then learn how to manipulate files. C++ provides the classes that can perform output and input of characters to/from files.
This unit will also cover namespaces, which group entities like classes, objects, and functions under a name. We will finish the unit with exception handling and preprocessor directives. Exceptions handle exceptional circumstances in our programs by transferring control to special functions called handlers. At the end of the unit, we will discuss the preprocessor directives, lines included in the code of a program that are not program statements but directives for the preprocessor.
Completing this unit should take you approximately 6 hours.
