“break”语句终止执行最内层的“for”、“switch”或“select”语句。
通常在switch语句和while、for、for...in、或do...while循环中使用break语句。
这是Go十大常见错误系列的第4篇:for/switch和for/select做break操作退出的注意事项。素材来源于Go布道者,现Docker公司资深工程师Teiva Harsanyi。
fmt.Println("This case is selected.")break//The following statement in this case will not execute.fmt.Println("After break statement")default: fmt.Println("This is the default case.") } 例如上面一段代码,即利用break跳出一个select循环 3、break用于嵌套循环 stopLable:for{ time.Sleep(p.Cfg.Wa...
在for -switch 和 for select 的 block中,如果用了break break出的是switch 和 select ,并不是break for 解决方法: 1 用 return 2 用 break tag; package main import "fmt" func main() { loop: for { switch { case true: fmt.Println("breaking out...") break loop } } fmt.Println("out!
The apparatus may also include a display responsive to break codes for showing which component of the group is currently connected to the single component. In embodiments in apparatus having break codes consisting of a sequence of one state longer than that found in any other digital code, the ...
for循环中的switch的break和continue作用范围 for循环中的switch的break和continue作用范围 不空泛的讲理论了,上代码.看下面这个代码: #include <stdio.h> #include <stdlib.h> int main () { char str[] = "SSSWLLIJKA"; char c; int k; for(k=2;(c=str[k]) != '\0';k++) { switch(c) { ...
loop: println(i) } goto test // 错误:label test not defined goto loop // 错误:goto loop jumps into block }和goto 定义跳转不同,break、continue 用于中断代码执行。break:用于 switch、for、select 语句,终止整个语句块执行。 continue:仅用于 for 循环,终止后续逻辑,立即进入下一轮循环。1...
