20Mastering Standard Library Algorithms
As Chapter 18, “Standard Library Containers,” shows, the Standard Library provides an impressive collection of generic data structures. Most libraries stop there. The Standard Library, however, contains an additional assortment of generic algorithms that can, with some exceptions, be applied to elements from any container. Using these algorithms, you can find, sort, and process elements in containers and perform a host of other operations. The beauty of the algorithms is that they are independent not only of the types of the underlying elements, but also of the types of the containers on which they operate. Algorithms perform their work using only the iterator or ranges interfaces, discussed in Chapter 17, “Understanding Iterators and the Ranges Library.”
The Standard Library comes with a large set of unconstrained algorithms, all working solely with iterators. These algorithms don't have any constraints in the form of concepts; see Chapter 12, “Writing ...
