When I was a kid, I found out that serious game programmers used C. So I convinced my dad to buy me a book on C and managed to get a C compiler for the family Mac 512k. But the book only covered the C language, and it didn't give me any example of using libraries! It taught me how to print "Hello, world" on a console (an alien concept on the Mac), but I couldn't for the life of me figure out how to create graphics or a UI with it, so I gave up. It wasn't until the arrival of the internet to my life that I discovered libraries. (and also "computer class" in high school was about word processing)
