C++ How to Program, 10/e

Summary

Section 6.1 Introduction

• Experience has shown that the best way to develop and maintain a large program is to construct it from small, simple pieces, or components. This technique is called divide and conquer (p. 212).

Section 6.2 Program Components in C++

• C++ programs are typically written by combining new functions and classes you write with “prepackaged” functions and classes available in the C++ Standard Library.

• Functions allow you to modularize a program by separating its tasks into self-contained units.

• The statements in the function bodies are written only once, are reused from perhaps several locations in a program and are hidden from other functions.

Section 6.3 Math Library Functions

• Sometimes functions are not ...
