Examines the use of the in-the-large language features of C++, which sometimes confuse even experienced programmers. The author demonstrates that unwarranted use of the more powerful language features may lead to cluttered programs which are harder to comprehend and sometimes less efficient than more straightforward alternatives.
- C++ supports programming-in-the-large, allowing relationships between different parts of a program to be expressed. The scope of C++ programming style therefore goes beyond traditional in-the-small issues which relate to the details of line-by-line coding. This book examines the use of the in-the-large language features of C++, which sometimes confuse even experienced programmers. The author demonstrates that unwarranted use of the more powerful language features may lead to cluttered programs which are harder to comprehend and sometimes less efficient than more straightforward alternatives. Cargill rewrites several programs, using techniques that range from improving consistency to removing redundant inheritance. The presentation simulates a code review, in which readers may independently evaluate and criticize alternative approaches to programming problems, and then compare their analyses with those of the author.
Design and coding style rules are distilled from the examples. Understanding and following these rules will help professional programmers design and write better C++ programs.
A chapter is devoted to each of the following topics:
- abstractions
- operator overloading
- consistency
- wrappers
- unnecessary inheritance
- efficiency
- virtual functions
Building on the programming rules introduced in the first seven chapters, Cargill presents a case study in which a single program undergoes repeated transformations that improve its overall quality while reducing its size. The book concludes with a chapter on multiple inheritance.
