If c starts at 0, then the loop condition c==9 is never true, and the
loop is never executed.

Looks like a fairly standard loop to me, except that I alwasy use curly
bracets on loops/conditionals. Skipping the bracets gets you in trouble
sooner or later when you update the code and forget to add them..

Thats the old way of doing things, prior to ANSI-C.

If you want to use ANSI-C then you don't need to call exit(). ANSI-C
defines the result of main as the programs exit code, unless terminated
by another way (exit call, killed or what ever).
