Go語言實現(xiàn)登錄驗證代碼案例

package main

import "fmt"

func main() {
	var name string
	var pwd string
	var loginChance = 3
	for i := 1; i = 3; i++{
		fmt.Print("請輸入用戶名：")
		fmt.Scanln(name)
		fmt.Print("請輸入密碼：")
		fmt.Scanln(pwd)

		if name == "zhangsan"  pwd== "123456" {
			fmt.Println("恭喜你登錄成功！")
			break
		} else {
			loginChance--
			fmt.Printf("你還有%v次登錄機會，請珍惜\n",loginChance)
		}
	}
	if loginChance == 0 {
		fmt.Println("機會用完，登錄失敗。")
	}
}
