16: Introduction to Templates

Inheritance and composition provide a way to reuse object code. The template feature in C++ provides
a way to reuse source code.

Although C++ templates are a general-purpose programming tool, when they were introduced in the language, they seemed to discourage the use of object-based container-class hierarchies (demonstrated at the end of Chapter 15). For example, the Standard C++ containers and algorithms (explained in two chapters of Volume 2 of this book, downloadable from are built exclusively with templates and are relatively easy for the programmer to use.

This chapter not only demonstrates the basics of templates, it is also an introduction to containers, which are fundamental components of object-oriented programming and are almost completely realized through the containers in the Standard C++ Library. You’ll see that this book has been using container examples – the Stash and Stack – throughout, precisely to get you comfortable with containers; in this chapter the concept of the iterator will also be added. Although containers are ideal examples for use with templates, in Volume 2 (which has an advanced templates chapter) you’ll learn that there are many other uses for templates as well.
