To get code coverage in C++

There are a few tools that help you get code coverage in C++. Arguably, the most popular is Gcov from GNU. It’s been around for years and works well with GCC and Clang. Although it does not work with Microsoft’s Visual Studio, using Clang to build and run software provides a viable alternative for Windows.
