Thread: getchar()

Im sorry to bother anyone.
I just started programming in C,and got a K&R to guide me.
The thing is.I made code that counts spaces, tabs and new lines.
Now the problem is,once i build and run everything,when i try to type something,it doesen't actually count anything.

Im just looking for some help.It would be really great if you could explain this to me.Sorry about this,i didn't have time to attach the actual file.
Here is the code:

Code:

#include <stdio.h>

main()
{
    int c, fl, fn, fb;

    fl = 0;
    fn = 0;
    fb = 0;


    while ((c = getchar()) != EOF) {
        if (c == ' ')
         ++fl;
        if (c == '\t')
         ++fn;
        if (c == '\n')
            ++fb;

   }
       printf ("d %d %d\n", fl, fn, fb);
}

It just opens the console and lets me write.But when i do type in text ,it doesen't do anything.Just gives me new line to write again.
The console is open until i close it manually.

One more thing.When i tryed to make like a simple copy program(copies whatever i type).If i use the while loop the program doesen't work,but if i were to use the for loop.It works perfect.

I did forget the %.I made that mystake ,thing is ,it still doesen't work for me.The TAB thing though,your right.
The thing is this doesen't end.The program just keeps going.Its like im in a notebad typing stuff.Nothing else.

Thank you for your help though.You did show me some ways .

It would help if you talked about "doesn't work" in disgusting detail. If people are getting vastly different results from you, now is an excellent time to get paranoid. If you get strange output, show that. If you enable a compiler option, show that. Do as much as you can. We're not psychic.

The problem I think is that hes not "ending the input" or generating an EOF character.

In windows you need to type Ctrl+Z after typing, once you do that THEN the program will output (your while() condition doesn't end until it hits EOF). In linux you
would do this by pushing Ctrl+D.

I showed the EOF char ^Z, being used as EOF on Windows, but I didn't specify the EOF as Ctrl+Z, which I should have. Thanks nonpuz for clarifying that.

Filster7 are you ending your input with Ctrl+z, and STILL it won't terminate?

It did work,thanks alot Adak.Your the greatest .
