Program Components in C++ • Modules: functions and classes • Programs use new and “prepackaged” modules – New: programmer-defined functions, classes – Prepackaged: from the standard library • Functions invoked by function call – Function name and information (arguments) it needs • Function definitions – Only written once – Hidden from other functions | 1 Chapter 3 - Functions Outline Introduction Program Components in C Math Library Functions Functions Function Definitions Function Prototypes Header Files Random Number Generation Example A Game of Chance and Introducing enum Storage Classes Scope Rules Recursion Example Using Recursion The Fibonacci Series Recursion vs. Iteration Functions with Empty Parameter Lists 2003 Prentice Hall Inc.
