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.

C++ Standard Library

While the conversion of a C string in a C++ string is done implicitly, we must explicitly request conversion from a C++ string into a C string. `str.copy()` copies the content of a C++ string without the terminating `\0` character. `str.data()` and `str.c_str()` include the terminating null character.

There are several ways to convert C++ strings to C strings. Let's go through them now.
