What is Standard Template Library?

SLT: Standard Template Library

The Standard Template Library (STL) is a software library for the C++ programming language that influenced many parts of the C++ Standard Library. It provides four components called algorithmscontainersfunctions, and iterators

The STL achieves its results through the use of templates. This approach provides compile-time polymorphism that is often more efficient than traditional run-time polymorphism. Modern C++ compilers are tuned to minimize abstraction penalties arising from heavy use of the STL.

There are four type of components in STL

  • Algorithms
  • Containers
  • Functions
  • Iterators

SLT functions List

Here are following points to be noted related to various functions we used in the above example:

  • The push_back( ) member function inserts value at the end of the vector, expanding its size as needed.
  • The size( ) function displays the size of the vector.
  • The function begin( ) returns an iterator to the start of the vector.
  • The function end( ) returns an iterator to the end of the vector.

That’s all, I hope this helped you!
