如果总尝试次数为3，请检查密码是否错误。 [英] check whether the password is wrong if total attempt are 3.

问题描述

我只想要while或for循环来检查输入错误的密码是否超过3次，然后请求Captcha请有人帮助我。我不想使用任何会话或数据库命令。

解决方案

一些伪代码：



< pre lang =text> passwordCorrect = false;
attemptCount = 0;

while（（attemptCount< 3）&（passwordCorrect == false））
{
pwd = getPassword
attemptCount ++
passwordCorrect = isPasswordCorrect（ pwd）
}

if passwordCorrect！= true
{
displayErrorMessage
QuitOrExitOrWhateverElseHere
}

请看这里：

但是请仔细阅读这篇关于安全的资料用C ++编写代码：

如何处理循环..？



你可以使用一个静态变量来存储服务数量

并在登录按钮点击事件检查其值，如果执行三个显示CAPTCHA ..

别忘了增加其值...

I just want the while or for loop for checking if the wrong password is entered more than 3 times, then ask for Captcha please someone help me. I don't want to use any session or database command.

解决方案

Some pseudocode:

passwordCorrect = false;
attemptCount = 0;

while ((attemptCount < 3) & (passwordCorrect == false))
{
   pwd = getPassword
   attemptCount++
   passwordCorrect = isPasswordCorrect(pwd)
}

if passwordCorrect != true
{
  displayErrorMessage
  QuitOrExitOrWhateverElseHere
}

But please carefully read this material about "Secure Coding in C++":

what to do with loops..?

you can use a static variable to store number of attepts
and in login button click event check its value, if exeeds three show CAPTCHA..
dont forget to increment its value...
