Explanation

Ctrl+C sends the SIGINT (Signal Interrupt) signal to the foreground process, which causes it to terminate immediately. This is the standard way to stop a running foreground process in a terminal. Ctrl+Z sends SIGTSTP, which suspends (pauses) the process and puts it in the background - it does not stop it. Ctrl+D sends an EOF (End of File) signal to the terminal's stdin, which closes the input stream but does not forcefully stop a running process. Ctrl+F has no standard terminal signal meaning.
