Can you name the main frameworks or libraries that come with C++ by default?

In C++, the standard library STL (Standard Template Library) is included by default, which comprises:

• Containers (vector, list, map, set, etc.)
• Algorithms (sorting, searching, copying, etc.)
• Iterators for traversing containers
• Smart pointers (std::unique_ptr, std::shared_ptr)

Besides STL, the standard library includes modules for working with threads, regular expressions, file systems, and more.

Unlike C#, which has a comprehensive set of frameworks in .NET, the basic set in C++ is primarily STL and standard libraries that come with the compiler.
