How to simulate an EOF?

I am currently reading K&R's book and typing in the examples from the first section, and there are a couple of examples such as this:

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

I am testing these examples on a Windows box and thus running the compiled exe files from the cmd prompt.

To test the example above, how do I simulate an EOF? That is, basically how can I make the loop stop when testing the example from the command prompt?

To enter an EOF, use:

  1. ^Z (CtrlZ) in Windows
  2. ^D on Unix-like systems

Refer EOF

Windows: Ctrl+Z
Unix :Ctrl+D

I had the same problem after pressing Ctrl+d program stopped and returned 0. If you use Clion press Ctrl+Shift+a than type Registry press enter and make sure run.processes.with.pty. is unchecked. After that compile program again and then you can type in input but don't press Ctrl+d on the same line as input it will return 0 or Error.
