A function template behaves like a function except that the template can have arguments of many different types (see example). In other words, a function template represents a family of functions. For example, the C++ Standard Library contains the function template max(x, y) which returns either x or y, whichever is larger. max() could be defined like this, using the following template:
In the first two cases, the template argument T is automatically deduced by the compiler to be int and double, respectively. In the third case deduction fails because the type of the parameters must in general exactly match the template arguments. This function template can be instantiated with any copy-constructible type for which the expression (y < href="http://en.wikipedia.org/wiki/Operator_overloading" title="Operator overloading">overloaded.
