使用if-else语句猜测一个数字

Posted 2021-04-05

我为猜数字游戏写了一个简短的PowerShell脚本。这看起来如下：

clear-host

$Guess = "11"

$response=read-host "Enter your guess"

if ($response -eq $guess)
{ 
    write-host "Congratulations"
}
else {
    write-host "Try again"
}

现在，如果我想这样做，经过一定次数的错误猜测，例如3次错误猜测程序将退出。我怎么能这样做？你能不能对这个问题有所了解？

答案

这是一个带有while循环的解决方案

$count = 0
$answered = $false
while ($count -lt 3 -and $answered -eq $false) {
    clear-host

    $Guess = "11"

    $response=read-host "Enter your guess"

    if ($response -eq $guess)
    { 
        $answered = $true
        write-host "Congratulations"
    }
    else {
        write-host "Try again"
    }
    $count++
}
