Best way to learn C is to use Turbo C IDE even though it is based on MS-DOS (obsolete) - you will need to open Windows Command Console. Turbo C v2.01 which is free download today was the best C compiler for ms-dos. The only problem is that the IDE editor commands are based on the old Wordstar word processor - use notepad++ for creating your program and make necessary change in the IDE. If you enter a function name like say 'strcmp' and position the cursor (key) over this and press Ctrl-F1 you will get a help window for the function - for a beginner this will prove more helpful than gedit (Or) vim / gcc / man pages in linux.
