I took the character counting program from the book, The C Programming Language 2nd ed, and it works fine on online compilers, but for some reason i get one extra count in eclipse. here is the program
#include <stdio.h>
int main(void)
long nc;
nc=0;
while (getchar() != EOF)
++nc;
printf ("%1d\n", nc);
return 0;
}
for example, if i input jkl, then hit enter, then terminate, I get the value of 4.
i also tried it in the for loop with the same result.
Any ideas whats going on here?
is it counting enter as a character?
if i dont hit enter it will print 0
is there a way to skip hitting enter and the terminate button?
also
if i printf("%d\n",EOF); it prints -1

This is not actually an Eclipse question, but a general C programming question instead. A better forum could be e.g. stackoverflow.
Please read your book once again: The newline (from the Enter key) *is* a chracter. The keyboard driver needs to know when the input line ends, so you do not get a bunch of characters without a newline ('\n').
