golang --for语句

Posted 2023-01-03 saryli

一条for 语句可以携带一条for子句。

for子句可以包含初始化子句、条件子句、后置子句。

package main

import (
	"fmt"
)

func main() 

	var number1, number2, number3 int
	for i := 0; i < 100; i++ 
		number1++
		fmt.Println(number1)
	

	var j uint = 1
	for ; j%5 != 0; j *= 3 //省略了初始化子句
		number2++
		fmt.Println(number2)

	

	for k := 1; k%5 != 0; //省略了后置子句
		k *= 3
		number3++
		fmt.Println(number3)

	

　

 

一条for语句可以携带一条range子句　

package main

import (
	"fmt"
)

func main() 

	ints := []int1, 2, 3
	for k, v := range ints 
		fmt.Println(k, v)
