exit 里的参数是你程序的返回值。
你想返回多少都行，一般是返回零表示正常退出，非零表示出现错误。

exit(0)正常退出，其他数值（包括1）表示你想显示的各种错误返回。

[prototype]

void exit(int status);
Terminates program normally. Functions installed using atexit are called (in reverse order to that in which installed), open files are flushed, open streams are closed and control is returned to environment. status is returned to environment in implementation-dependent manner. Zero or EXIT_SUCCESS indicates successful termination and EXIT_FAILURE indicates unsuccessful termination. Implementations may define other values.

usually, EXIT_SUCCESS == 0, EXIT_FAILURE = 1.
