Example C Programs

Here are a bunch of short example C programs.

• Programs from the textbook
• hello.c, the traditional "Hello world!" program, copied out of the textbook.
• depth.c, the "depth" program from chapter 1, copied out of the textbook.
• mycat.c, which does the same job as the "cat" command, at least in a simple form: with no arguments, it copies stdin to stdout, and with one argument, it copies the specified file to stdout.
• mycat2.c, a more general version that allows more than one file. It's also restructured to use a "dumpfile" function rather than doing the copying in-line.
• clongword.c, which finds the longest word in stdin.
• clongword2.c, which also finds the longest word in stdin, but it uses scanf rather than reading character by character.
• clongword3.c, which does the exact same thing, but is a little more "bulletproof" in that it refuses to read a longer word than it has space for. Demonstrates use of sprintf.
