A graphics library is needed. The old way in C was to use Turbo C and the graphics.h library that supported drawing.For Visual Studio, there is Win32, C++, and GDI as this youtube video points out: https://www.youtube.com/watch?v=WmSuwojt3nw, but it is not C. GTK and IUP are a couple of graphical libraries that work with C.
