Does C++ support threads natively?
Starting from C++11, C++ does support threads natively, and it is generally referred to as the C++ thread support library. The C++ thread support library provides an abstraction over the POSIX pthreads C library. Over time, C++ native thread support has improved to a greater extent.
I highly recommend you make use of the C++ native thread over pthreads. The C++ thread support library is supported on all platforms as it is officially part of standard C++ as opposed to the POSIX pthread
 library, which is only supported on Unix, Linux, and macOS but not directly on Windows.
The best part is thread support has matured to a new level in C++17, and it is poised to reach the next level in C++20. Hence, it is a good idea to consider using the C++ thread support library in your projects.
