Explore the full potential of C++ by mastering the standard library.

Become a C++ Programmer

The C++ standard library is a collection of all the tools and utilities available in C++. It received its latest update in 2017, known as C++17. The update introduces many new features that further optimize our code. This module will help us fully grasp C++ and use it to its full potential.

C++ Standard Library

## 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](http://en.cppreference.com/w/cpp/algorithm/min), [std::max](http://en.cppreference.com/w/cpp/algorithm/max) and [std::minmax](http://en.cppreference.com/w/cpp/algorithm/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.

This family of functions allows us to find the minimum and maximum in a set of data. Let's find out how.
