control -d是stdin的默认停车标志吗？ 在Linux C中？

Question

is control-d a default stop sign for stdin?

In our homework, it says command-d will be stop inputting.

Is it a default ?

Answer 1

Ctrl-D on Linux terminal with default settings is an end-of-file marker for stdin.

See also the tty demystified and the stty(1) command (and termios(3) ...). Use eg feof(3) after some stdio operation, or compare the result of getc(3) with EOF (etc....) to detect end-of-file conditions!
