To eat the '\n' from the Enter key.
Note that cK is of type int and not char,
to match the return type of getchar.

Zorna Cutura explained it pretty good.
The idea, is to convert text lines into strings.
Text files and streams are made of lines.
A line is like a string, except that a line is
teminated by a '\n' character,
and a string is terminated by a '\0' character.

There should be
fflush(stdout);
after that fputs.
