Why is getchar() not working for me?

c, getchar

Solution

You have to finish the input. Your program will count characters until `EOF` is encountered. `EOF`, in the keyboard, can be sent by pressing Ctrl-Z then ENTER if you are in Windows, or Ctrl-D then ENTER if you are in Linux/OS X.

Problem

I've just started programming c and I'm working through The C Programming Language by Brian W.Kernighan and Dennis M.Richie. One of the first examples is character counting and the following program is given, but when I enter a string no result it printed. ``` #include <stdio.h> main() { long nc; nc = 0; while (getchar() != EOF) ++nc; printf("%ld\n",nc); } ``` Why isn't this working?
