“返回0"与“返回0"之间的差异和“退出(0)"； [英] Difference between "return 0" and "exit (0)"

问题描述

在函数中使用时，return 0和exit (0)之间是否有区别? 如果是，我应该何时在函数中使用return 0或exit (0)?

Is there any difference between return 0 and exit (0) when using in a function? If yes, When should I use return 0 or exit (0) in a function?

推荐答案

return从函数中退出，而exit从程序中退出.

return exits from the function while exit exits from the program.

在main函数中执行return 0;语句或调用exit(0)函数将调用已注册的atexit处理程序，并导致程序终止.

In main function executing return 0; statement or calling exit(0) function will call the registered atexit handlers and will cause program termination.
