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. MSVC is proprietary software; it was originally a standalone product but later became a part of Visual Studio and made available in both trialware and freeware forms. It features tools for developing and debugging C++ code, especially code written for Windows API, DirectX and .NET Framework.
