Go language goto statement
Go language goto statement unconditionally transferred to the process specified line.
goto statement is generally used in conjunction with conditional statements. It can be used to implement a conditional branch, constitute cycle, out of the loop body functions.
However, in the structure of the program design generally do not advocate the use of the goto statement, program flow in order to avoid confusion, make comprehension difficult to produce and debug programs.
grammar
goto syntax is as follows:
goto label; .. . label: statement;
break statement is a flow chart is as follows:
Examples
package main
import "fmt"
func main() {
/* 定义局部变量 */
var a int = 10
/* 循环 */
LOOP: for a < 20 {
if a == 15 {
/* 跳过迭代 */
a = a + 1
goto LOOP
}
fmt.Printf("a的值为 : %d\n", a)
a++
}
}
The above examples Implementation of the results:
a的值为 : 10 a的值为 : 11 a的值为 : 12 a的值为 : 13 a的值为 : 14 a的值为 : 16 a的值为 : 17 a的值为 : 18 a的值为 : 19
