ProbIem with EOF in C

Question

I\'m writing a program which is supposed to read two strings that can contain line breaks and various other characters. Therefore, I\'m using EOF (Ctrl-Z or Ctrl-D) to end t

Answer 1

What you are trying is fundamentally impossible with EOF.

Although it behaves like one in some ways, EOF is not a character in the stream but an environment-defined macro representing the end of the stream. I haven't seen your code, but I gather you're doing is something like this:

while ((c=getchar()) != EOF) {
    // do something
}
while ((c=getchar()) != EOF) {
    // do something else
}

When you type the EOF character the first time, to end the first string, the stream is irrevocably closed. That is, the status of the stream is that it is closed.

Thus, the contents of the second while loop are never run.
