C++编程中,哪些需要return 0,哪些不用
比较严格的说,返回值类型不为void的,可以正常返回的函数,所有的return语句都必须要有返回值。return 0; 仅仅适用于返回值类型是int,double,void*这样可以用0表示的函数(比如int main)。反之,返回值类型是void的函数不需要return 0;,甚至不需要return(会自动return)。所有路径都抛出异常的函数也不需要return。
return 0到底是什么意思,什么用途什么地方必须要用到它
return 0是函数的返回值,函数中要写明return 0,表示返回。因为函数(除void)在遇到return时才能返回。一定要有,代表程序结束。
用途:return 0用来告知程序的结束。
必须有的地方:如果函数类型是int,则必须输入return 0。若函数类型是void,则可以不输入return 0。
扩展资料
return 表示从被调函数返回到主调函数继续执行,返回时可附带一个返回值,由return后面的参数指定。 return通常是必要的,因为函数调用的时候计算结果通常是通过返回值带出的。
如果函数执行不需要返回计算结果,也经常需要返回一个状态码来表示函数执行的顺利与否(-1和0就是最常用的状态码),主调函数可以通过返回值判断被调函数的执行情况。
如果函数名前有返回类型定义,如int,double等就必须有返回值,而如果是void型,则可以不写return,但这时即使写了也无法返回数值。
