    sumtimes the program is taking ctrl+c as EOF but other times as kill command..

    thts y i m curious abt wat's actually happening

    btw where have u posted the corrected program
    Right here:
    pls help urgently

    Your program wouldn't end right because you had EOF with single quotation marks, around them.

    We told you that, and we told you that was wrong, and we posted the corrected program code.

    But you argue on...

    Ctrl + c just *SEEMS* like it works - but here's the thing: the keyboard buffer is only read and gives input to the operating system, so many times each second. So when you press ctrl + c it may *seem* like it's acting differently, maybe like it's being accepted as EOF by your program:

    It is not!

    It's just that exactly *when* your program is terminated by the ctrl+c, is not going to always be at exactly the same moment, each time. Each keystroke has to be intercepted and read by the OS, and then put into a queue to have that request, done.

    How about something else?

    Code:
    #define ESC 27  //just below your #include files - note - no semi-colon!
    
    int c = 0;
    while((c=getchar()) != ESC) {
       //any other loop logic, in here
    }
    Try that and see if you like it.

    ^C
    c:\MinGW\bin

    ^Z is actually ctrl +Z
    so u can see the program doesnt take @ctrl+z as EOF
    so i tried using ctrl+c..sumtimes it gets executed sumtimes it isnt thts wat bothers me
    i use a MinGW compiler with no ide...i donno whether visual studio ide w'd work...
    Ok. I dont know how to work with Mingw but I guess this is what you're doing wrong.
    You're entering a string like "my name is rickyCtrl+ZCtrl+C"(without double quotes), i.e you're entering ctrl+Z in the same line where the string ends along with ctrl+C followed by it. So the result is ctrl+C terminates the program and the output is 0(for all).
    Now do this as I say(exactly)
    1.Input your string in the first line.
    2. Press Enter where your string ends.
    3.Now in the nextline(important), press Ctrl+Z
    4. Again press Enter, you'll get the correct output.
    Try it and tell us if it solves the problem.
    PS: This is just a wild guess of what you're doing.
    HOPE YOU UNDERSTAND.......

    It's fine to celebrate success but it is more important to heed the lessons of failure

    Please, try to avoid the use of 'text speak' in the forums; abbreviated writing is not particularly helpful, and many people find it extremely annoying. In fact, many tech forums forbid the use of this kind of thing. For myself, I am not inclined at all to help people who refuse to type words properly, because I cannot take them seriously. Relating to this, Eric Raymond maintains an article called How to Ask Questions the Smart Way. You will find there some useful advice regarding asking for help on the internet. If you practice what you read, I am fairly certain you will not be annoying people nearly as much as you did in this thread. In particular, read this section:

    Write in clear, grammatical, correctly-spelled language

    Until you can build a working general purpose reprogrammable computer out of basic components from radio shack, you are not fit to call yourself a programmer in my presence. This is cwhizard, signing off.
