The min, max and minmax functions

Required Headers

The many variations of the min, max, and minmax functions apply to values and initializer lists. These functions need the header <algorithm>. Nearly the same holds for the functions std::move, std::forward and std::swap. You can apply them to arbitrary values. These three functions are defined in the header <utility>.

std::min, std::max and std::minmax

The functions std::min, std::max and std::minmax, defined in the header <algorithm>, act on values and initialiser lists and give you the requested value back as result. In the case of std::minmax, you get an std::pair. The first element of the pair is the minimum, the second is the maximum of the values. By default, the less operator (<) is used, but you can specify your comparison operator. This function needs two arguments and returns a boolean. Functions that either return true or false are called predicates.
