Templates are of great utility to programmers in C++, especially when
combined with multiple inheritance and operator overloading. The C++
Standard Template Library (STL) provides many useful functions within a
framework of connected templates.
As the templates in C++ are very expressive they may be used for things other than generic programming. One such use is called template metaprogramming, which is a way of pre-evaluating some of the code at compile-time rather than run-time. Further discussion here only relates to templates as a method of generic programming.
There are two kinds of templates. A function template behaves like a function that can accept arguments of many different types. For example, the C++ Standard Template Library contains the function template max(x, y) which returns either x or y, whichever is larger. max() could be defined like this: more...
