Document Summary
Obfuscated = render obscure, unclear or unintelligible. See sds. c completely illegible, still compiles. Within main function argv = array of arguments. In the context of the main function. Return 0 == exit 0: similar to java java copied the best of c, #include use declarations of functions, first line are librarys included. Stdio. h has printf: each c program has a main function. Returns an int = 0 if no errors, else errors: have to declare variables & types. Statically type language: functions must be. Declared tells compiler how to use function. Defined creates the item: declarations must appeare before code, uninitialized variables have no default value, no run-time checking, no polymorphism. To compile c on unix based machine: gcc wall -g -o [cprogramname] [cprogramname]. c. Basic controll structures: for loop like java. For (int i is illegal in ansi c. Fprintf can print to a file, printf prints to standard output.
