Go语言实现登录验证代码案例

package main

import "fmt"

func main() {
	var name string
	var pwd string
	var loginChance = 3
	for i := 1; i <= 3; i++{
		fmt.Print("请输入用户名：")
		fmt.Scanln(&name)
		fmt.Print("请输入密码：")
		fmt.Scanln(&pwd)

		if name == "zhangsan" && pwd== "123456" {
			fmt.Println("恭喜你登录成功！")
			break
		} else {
			loginChance--
			fmt.Printf("你还有%v次登录机会，请珍惜\n",loginChance)
		}
	}
	if loginChance == 0 {
		fmt.Println("机会用完，登录失败。")
	}
}
