void f (int); void f (char const*);
With function templates, one overloads on type patterns such as pointer-to-T or Array<T>:
template<typename T> void f(T*); template<typename T> void f(Array<T>);
Given the prevalence of type traits (discussed in Chapter 19), it is natural to want to overload function templates based on the properties of the template arguments. For example:
template<typename Number> void f(Number); // only for numbers template<typename Container> void f(Container); ...
