<C new> - question about an example in C: The Programming Language

I'm a total newb to C. I bought C: The Programming Language to start learning, but I have a question about a couple examples, one to count characters, the other to count lines. They're not printing anything, and I'm not sure why. I've double and triple checked everything, making sure I have exactly what's in the book, but to no avail. I'm using Code Blocks 8.02 and Vista.

Code:

#include <stdio.h>

/* count characters in input; 1st version */
main()
{
    long nc;
    
    nc = 0;
    while (getchar() != EOF)
        ++nc;
    printf("%1d\n", nc);
}

The second example, the second version, doesn't work either.

Code:

#include <stdio.h>

/* count characters in input; 2nd version */
main()
{
    double nc;
    
    for (nc = 0; getchar() != EOF; ++nc)
        ;
    print("%.0f\n", nc);
}

The third is the line counting one

Code:

#include <stdio.h>

/* count lines in input */
main()
{
    int c, n1;

    n1 = 0;
    while ((c = getchar()) != EOF)
        if (c == '\n')
            ++n1;
    printf("%d\n", n1);
}

Any help is appreciated, of course. Thanks.

They both rely on End-Of-File (EOF) being presented to the application. If you are typing by hand, then you need to end it with CTRL-Z (on windows, it's CTRL-D on Linux/Unix [and probably recent versions of MacOS too]).

Awesome, that's exactly what I was missing. Thanks a ton. I'll be sure to bring my questions as I learn C to this forum.

Also you're missing all your curly braces in those for, while and if statements.

But they are not necessary for one-line code. Good practice or not, I really don't see a problem when people write a single line without the { and }.

Yeah, teaching newbies bad habits is a really good idea...

That's if you consider it bad practice. I don't
I digress anyway. It's not like I'll force any ideas upon someone.

I'm in the same boat by saying it's not bad practice

You have to learn somehow, plus indentation should help you.
