在显示最终得分后，它不显示IQ结果。请帮忙。这是完整的程序...我使用箭头来显示拒绝编译的开关块

答案 0 :(得分：1)
对于你的特定情况，使用if / else总是更好，使用switch语句你不能在这种情况下使用条件。看起来您正在检查范围，如果范围是常数，那么您可以尝试以下
if (FinalScore == 40)
{
Console.WriteLine("You are a genius");
}else if (FinalScore >= 35)
{
Console.WriteLine("You are intelligent");
}else if (FinalScore >= 22)
{
Console.WriteLine("Your IQ level is average");
}else if(FinalScore >= 10)
{
Console.WriteLine("Your IQ level is below average");
}else
{
// something else
}
答案 1 :(得分：1)
你应该使用If else语句来做你想做的事情，你可以通过使用这样的三元语句来缩短你的代码，
Console.WriteLine((FinalScore >= 40) ? "You are a genius" :
(FinalScore >= 35) ? "You are intelligent" :
(FinalScore >= 22) ? "Your IQ level is average" :
(FinalScore >= 10) ? "Your IQ level is below average" : "You are really below average");
//The really below average would be your something else referenced above.
答案 2 :(得分：0)
您的代码编译得很好。
如果您记录了该交换机块的默认情况，您会看到40实际上是无法访问的情况。你的公式保证永远不会产生40 - 由于奖励积分，所有4个正确值都是50分。所有错误都不会产生结果。
有效案例为：0, 10, 22, 35, 50。您只考虑10, 22, & 35。
default:
// this would've thrown an exception for FinalScore==50
throw new Exception("unexpected score of " + FinalScore);
