Function Templates

Abstract

You may have noticed that some of the overloaded functions in Ex8_15 consisted of exactly the same code. The only difference were the types that appear in the parameter list. It seems an unnecessary overhead to have to write the same code over and over, just because it has to work for different types. And indeed it is. In such situations you can write the code just once, as a function template. The Standard Library, for instance, makes heavy use of this feature to ensure that its functions work optimally with any type, including your own custom types, which of course the library cannot know about in advance. This chapter introduces the basics of defining your own function templates that work with any type you desire.
