So I've started in learning OpenGL , then I found the NeHe website and its Legacy Tutorials (here is the link http://nehe.gamedev.net/tutorial/lessons_01__05/22004/ ).But the problem is that I can't download any examples of code ( neither C code examples nor any other language ) .As you see it is impossible to download http://nehe.gamedev5.net/data/lessons/pelles_c/lesson01.zip . Does anyone has expamles of C code of this lessons ? And the second question. If I prefer coding on C , should I choose GLUT but not an OpenGL ?
