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

`std::prev_permutation` and `std::next_permutation` return the previous smaller or next bigger permutation of the newly ordered range. If a smaller or bigger permutation is not available, the algorithms return `false`. Both algorithms need bidirectional iterators. Per default the predefined sorting criterion `std::less` is used. If you use your sorting criterion, it has to obey the [strict weak ordering](https://en.wikipedia.org/wiki/Weak_ordering). If not, the program is undefined.

Applies the previous permutation to the range: 

We can see the different permutations in a range using C++.
