Beginners in C++ will never know how easy life can get without a bit of knowledge of the Standard Template Library. Many of us who have a bit of grounding in Java realise how the Java API makes lives easier for Java programmers and how just a few lines of code achieves quite complex tasks.
Well, the C++ counterpart can be it's Standard Template Library. It provides C++ programmers with a comprehensive set of efficiently implemented tools and facilities that can be used for most types of applications.
The STL is the nucleus of the C++ standard library, providing the standard containers and algorithms, and the framework for their use and their extension with user-defined containers and algorithms
STL is basically a C++ library of container classes, algorithms, and iterators; it provides many of the basic algorithms and data structures of computer science. The STL is a generic library, meaning that its components are heavily parameterized: almost every component in the STL is a template. You should make sure that you understand how templates work in C++ before you use the STL.
