    Character counting issues from Kernighan text

    I've just started to learn C programming, using book 'The C Programming Language' by Kernighan and Ritchie.

    I'm on 1.5.2, and the following program (provided in the book) is supposed to count characters that I type in:

    Code:
    #include <stdio.h>
    
    /* count characters in input; 1st version */
    main()
    {
        long nc;
    
        nc = 0;
        while (getchar() != EOF)
            ++nc;
        printf("%ld\n", nc);
    }
    However, when I build and run the program (using Code::Blocks and Pelles C IDE compilers), the program does not count and display the characters I input.

    On Code::Blocks, I received no warnings or errors when compiling, but on Pelles, I received the following warning on compilation:
    C:\Users\...\Documents\cpractice2\cpracticeb1.5.2. c(4): warning #2099: Missing type specifier; assuming 'int'.

    I would like to know what may be wrong. Thanks.

    It's not supposed to (re)display the characters you type, just the total number, which it does. I'm guessing your issue is "how do I type EOF at my computer", which given you are on windows is "type Ctrl-Z on a line by itself".

    (As to the warning, back in the old days you could just leave int off in a surprising number of places. Nowadays, not so much.)
