So, I want to learn a moderate amount of 3 programming languages, C, C++ and C#. I already know a moderate amount of C# but I also want to learn C and C++, as well as observe how all 3 languages compare to each other. Would it be helpful if I downloaded 3 separate compilers and took a programming tutorial that involved all three programming languages? For example, Wikipedia has an article on Hello World statements for C, C++ and C#.

The two problems I can think of is that I might not be able to find a modern C compiler due to its decline in popularity and that I would need to look for a series of tutorials that dealt with all 3 languages specifically.

Thanks.
