    Well for a start, nowhere in your assignment does it say to use getchar().

    Perhaps you can start with that.

    The bit about scanf and EOF means you should be doing something like
    Code:
    while ( scanf("%d",&myint) != EOF ) {
      // do something
    }
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    I don't understand the eof part.


    End-of-file - Wikipedia


    While ( !eof ) { }

    While Not End Of File
