Do I need to keep old versions of Visual C++?
Versions upon versions There are multiple different versions of Visual C++ Redistributable. Unfortunately, newer ones don’t supersede older ones. For example, the Visual C++ 2015 Redistributable doesn’t automatically replace the Visual C++ 2010 Redistributable. Both may be needed.
Is it safe to uninstall old versions of Microsoft Visual C++?

Is it OK to uninstall Microsoft Visual C ++?
You can uninstall them, however some applications might need them installed to run correctly. These applications will usually let you know if they depend on the C++ packages when you try to install/run them. I would recommend leaving the latest package installed though.
Can C code be used in C++?
If you are compiling the C code together, as part of your project, with your C++ code, you should just need to include the header files as per usual, and use the C++ compiler mode to compile the code – however, some C code won’t compile “cleanly” with a C++ compiler (e.g. use of malloc will need casting).
Is C code compatible with C++?
C++ is a subset of C as it is developed and takes most of its procedural constructs from the C language. Thus any C program will compile and run fine with the C++ compiler. However, C language does not support object-oriented features of C++ and hence it is not compatible with C++ programs.
