4: int main()

5: {

6: char ch;

7: while ( (ch = std::cin.get()) != EOF)

8: {

9: std::cout << “ch: “ << ch << std::endl;

10: }

11: std::cout << “\nDone!\n”;

12: return 0;

To exit this program, you must send end of file from the keyboard. On DOS

computers, use Ctrl+Z; on Unix workstations, use Ctrl+D.

TIP

Hello

ch: H

ch: e

ch: l

ch: l

ch: o

ch:

World

ch: W

ch: o

ch: r

ch: l

ch: d

ch:

^Z (ctrl-z)

Done!

On line 6, a local character variable,ch, is declared. The whileloop assigns the

input received from cin.get()to ch, and if it is not EOF, the string is printed out.
