    EOF isnt working....

    #include <stdio.h>
    int main(void)
        int c, d;
        while((c = getchar() - '0') != EOF)  {
             if(c == 2)
               printf("fool\n");   /* once again, my pointless messages */
             if(c == 1)
    U r suppose to press F6 to end this program right? but it wont terminate for some reason...

    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*

    You would need your while condition to be
    "while((c = getchar() - '0') != EOF-'0')

    Because you are subtracting '0' from getchar() before testing for EOF.
    It is too clear and so it is hard to see.
    A dunce once searched for fire with a lighted lantern.
    Had he known what fire was,
    He could have cooked his rice much sooner.
