main（）的函数返回值？ [英] main() functions return value?

问题描述

任何人请告诉我哪里有'C'语言的main（）函数返回它的价值？

Anyone please tell me where the main() function of the 'C' language returns its value?

推荐答案

C'S 主函数返回一个int ...这INT变到执行它的程序（的父进程，如果你愿意）作为退出状态code。

C's main function returns an int... that int goes to the program which executed it (the parent process, if you will) as an exit status code.

具体而言，在大多数操作系统，0退出code表示正常运行（没有真正的错误），和非零意味着出现了一个问题，该方案有异常退出。

Specifically, on most operating systems, a 0 exit code signifies a normal run (no real errors), and non-zero means there was a problem and the program had to exit abnormally.
