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

A string can read from an input stream via `>>` and write to an output stream via `<<`.

The global function `getline` empowers us to read from an input stream line by line until the *end-of-file* character. 

There are four variations of the `getline` function available. The first two arguments are the input stream `is` and the string `line` holding the line read. Optionally we can specify a special line separator. The function returns by reference to the input stream. 

Strings are well-known for their use in input and output of data. Let's look at how this is done.
