Let's dive into some of the milestones in C++'s long history.

We'll cover the following

The C++ standard library consists of many components. This chapter serves two purposes. It should give you a quick overview of the components and an idea of how to use them.

The History

C++ and therefore the standard library have a long history. C++ started in the 1980s of the last millennium and ended now in 2017. Anyone who knows about software development knows how fast our domain evolves. So 30 years is a very long period. You may not be so astonished that the first components of C++, like I/O streams, were designed with a different mindset than the modern Standard Template Library (STL). This evolution in the area of software development in the last 30 years, which you can observe in the C++ standard library, is also an evolution in the way software problems are solved. C++ started as an object-oriented language, then incorporated generic programming with the STL and now has adopted a lot of functional programming ideas.
