How are Boost libraries useful in c plus plus?

Answer 1

Third-party C++ libraries in general are very useful. They provide us with types, algorithms and utilities that are not provided by the standard library alone and save us from continually having to "reinvent wheels". The standard library is specifically intended to be used by the vast majority of programmers across all fields of programming, whereas third-party libraries tend to be more specialised, providing support for graphics, sound and other proprietary hardware as well as types and algorithms that have more limited uses. However, although the Boost library is highly-specialised across a wide range of programming disciplines, many of its features have been incorporated into the standard library over the years. In some ways, the Boost library can be seen as a test-bed for future versions of the standard library as well as the language itself. However, due to its specialised nature, it will always remain separate from the standard library. Nevertheless, the Boost library is widely used and, if there's a feature you require that is not provided by the standard library, you will invariably find the Boost library either provides that feature directly or a third-party library makes use of the Boost library in order to provide that feature.
