How to set up Visual Studio IDE for programming competitions?

Question

visual studio

At the moment I'm solving student olympiads in C++ programming, I have all the solutions of problems in different projects (I want to save them), it eats a lot of disk space because of the IDE index, which is stored in a file for each project, and it takes a lot time to create projects. I had experience in Java, and there you can put many classes in different packages into one project and run their main methods from Intellij Idea. The question is, is there any functionality in the Visual Studio IDE (not Code) that makes the launch of the active file? Maybe there is a plugin to compile and run the active file, I can’t find it yet.

Answer 1

I would make a test project, and in each test I would call one function.
