Explore the full potential of C++ by mastering the standard library.

Become a C++ Programmer

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.

### Streams
A stream is an infinite data stream on which you can push or pull data. String streams and file streams enable strings and files to interact with the stream directly.

### String Streams 

String streams need the header `<sstream>`. They are not connected to an input or output stream and store their data in a string.

Whether you use a string stream for input or output or with the character type `char` or `wchar_t` there are various string stream classes: 

|Class|Use|
|-|-|
|`std::istringstream` and `std::wistringstream`|String stream for the input of data of type `char` and `wchar_t`.|
|`std::ostringstream` and `std::wostringstream`|String stream for the output of data of type `char` and `wchar_t`.|
|`std::stringstream` and `std::wstringstream`|String stream for the input or output of data of type `char` and `wchar_t`|


Typical operations on a string stream are:

* Write data in a string stream:
