RE: [Dev-C++] Newbie Question.

[Per W. <pw...@ia...>]

It is a bit easier to count number of characters in the file if you move
your nl++ inside the braces.

EOF works just as in all other C libraries. EOF is defined as -1 and that
is the return value of getchar() after last character has been read.

For windows:
type myfile | my_eof_program

For Unix:
cat myfile | ./my_eof_program

should work. At least my terminals stays open if I run the program
directly and enters text and end it with Ctrl-D. However, if I press
Ctrl-D a second time, i.e. when I'm on the command line, I will loose my
window.
