What is the main purpose of STL?

The Standard Template Library (STL) is a set of C++ template classes to provide common programming data structures and functions such as lists, stacks, arrays, etc. It is a library of container classes, algorithms, and iterators. It is a generalized library and so, its components are parameterized.

In what form does the STL provides?

In what form does the STL provides heap? Explanation: STL does provide a heap in the form of a std::priority_queue.

What is the property of stable sort function provided by the STL?

What are major components of STL?

STL contains five kinds of components: containers, iterators, algorithms, function objects and allocators.

What are STL containers?

An STL container is a collection of objects of the same type (the elements). Container owns the elements. Creation and destruction is controlled by the container.

Is STL sort stable?

Godbolt. As of September 2020, it appears that libc++ std::sort happens to be stable for all ranges of size less than 31, and libstdc++ std::sort happens to be stable for all ranges of size less than 17. (Do not rely on this little factoid in production!)
