detecting and of input

I am wondering if there is any way to detect the end of a user's input in a console app without having to use a sentinel character. Will someone please help me?

Well in C, its

Code:

---

while ( fgets( buff, sizeof buff, stdin ) != NULL ) {
    // do stuff
}

---

I imagine that the cin.getline() or whatever functions return some useful status to indicate end of file.

You normally signal EOF on stdin by typing either ctrl-z or ctrl-d (depending on your OS)

Yep, istreams have an implicit conversion that allows simple status checking:

Code:

---

while ( cin.getline ( buff, sizeof buff ) ) {
  // Do stuff
}

Perhaps he wants to know if he read the whole line, inwhich case he needs to check to make sure the last character is '\n'. If you use a loop it will keep on begging for input until they give EOF (or an error occures) which is usually not what someone desires.

thanks a lot orbitz
