Thank you very &nbsp;much, Means STL library &nbsp;is already &nbsp;with Visual C++ 2012

STL is a source library which consists of header files. this is because STL classes are template classes which cannot be compiled without a concrete type. for example a vector is a template array which can compiled only if you define it with a type, e. g. &nbsp;vector&lt;int&gt; because of that all implementation code of a STL class was provided with the headers.<br />

STL comes with VS since VC 6.0 which was from 1998. that was a few months before the official release of c++ standard (where STL was the main part of).<br />

Microsoft Visual C++ (often abbreviated as MSVC or VC++) is an integrated development environment (IDE) product from Microsoft for the C, C++, and C++/CLI programming languages. It features tools for developing and debugging C++ code, especially code written for the Microsoft Windows API, the DirectX API, and the Microsoft .NET Framework. Many applications require redistributable Visual C++ packages to function correctly and are often installed independently of applications, allowing multiple applications to make use of the package while only having to install it once
