Projections with Ranges

The algorithms of the ranges library are lazy, can work directly on the container, and can easily be composed. But they have more to offer: projections. A projection is a mapping of a set into a subset. Let me show you in this post what that means:

The Ranges Library in C++20: More Details

Thanks to the ranges library, working with the Standard Template Library (STL) is much more comfortable and powerful. The algorithms of the ranges library are lazy, can work directly on the container, and can easily be composed. But there is more to it:

C++20: The Ranges Library

Thanks to the ranges library in C++20, working with the Standard Template Library (STL) will become much more comfortable and powerful. The algorithms of the ranges library are lazy, can work directly on the container and can easily be composed. To make it short: The comfort and the power of the ranges library are due to its functional ideas. Let me show you what that means.
