休息声明

break语句用于中断发生它的最内部结构。它可以用于for循环(计数器,条件等)以及开关中。在该结构的结尾}之后继续执行。

句法:-

break;

中断声明示例:

package main
import "fmt"
func main() {
   var  a int = 1
   for a < 10{
      fmt.Print("Value of a is ",a,"\n")
      a++;
      if a > 5{
         /* terminate the loop using break statement */
         break;
      }
   }
}

输出:

Value of a is 1
Value of a is 2
Value of a is 3
Value of a is 4
Value of a is 5

Break语句也可以应用在内部循环中,并且控制流爆发到外部循环中。

带有内循环的中断声明:

package main
import "fmt"
func main() {
   var a int
   var b int
   for a = 1; a <= 3; a++ {
      for b = 1; b <= 3; b++ {
         if (a == 2 && b == 2) {
            break;
         }
         fmt.Print(a, " ", b, "\n")
     }
   }
}

输出:

1 1
1 2
1 3
2 1
3 1
3 2
3 3
