为什么我不能在If语句中定义多个相等的变量？

我想设置不同的时间相等，以便我可以继续与其他语句。但由于某种原因，它似乎不想这样做。不仅如此，它似乎只承认我拥有的第一个“TIE”，即使它也应该承认其他的。我究竟做错了什么？为什么我不能在If语句中定义多个相等的变量？

if (time1 < time2 && time3) 
{ 
    cout << "\nCongratualations " << racer1 << "!!! " << "You are the winner!!" << endl; 
    cout << "\n***** Your winning time is: " << time1 << " *****" << endl; 
} 
else if (time2 < time1 && time3) 
{ 
    cout << "\nCongratualations " << racer2 << "!!! " << "You are the winner!!" << endl; 
    cout << "\n***** Your winning time is: " << time2 << " *****" << endl; 
} 
else if (time3 < time1 && time2) 
{ 
    cout << "\nCongratualations " << racer3 << "!!! " << "You are the winner!!" << endl; 
    cout << "\n***** Your winning time is: " << time3 << " *****" << endl; 
} 
else if ((time1 == time2) < time3) 
{ 
    cout << "\nWe have a TIE " << racer1 << " and " << racer2 << " win!!" << endl; 
    cout << "\n***** Your winning time is: " << time1 << " *****" << endl; 
} 
else if ((time2 == time3) < time1) 
{ 
    cout << "\nWe have a TIE " << racer2 << " and " << racer3 << " win!!" << endl; 
    cout << "\n***** Your winning time is: " << time2 << " *****" << endl; 
} 
else if ((time3 == time1) < time2) 
{ 
    cout << "\nWe have a TIE " << racer1 << " and " << racer3 << " win!!" << endl; 
    cout << "\n***** Your winning time is: " << time3 << " *****" << endl; 
} 
if (time1 == (time2 == time3)) 
{ 
    cout << "\nWe have a 3 way TIE!! No winner for this Race..." << endl; 
    cout << "\n***** Your winning time is: " << time1 << " *****" << endl; 
}

请取消您的Wall Of Code并将其替换为仅包含重现问题所需代码的简化示例。 –

它看起来像你正在编写的代码基于你有*猜测*语法的手段来表示。这只会让你陷入麻烦。这里值得回到基础知识来了解每个操作符*实际*所做的事情。 –

此：(time1 < time2 && time3)意味着time1大于time2和time3为真（非零）。

什么你大概的意思是：(time1 < time2 && time1 < time3)

这：(time1 == (time2 == time3))意味着time1等于真（1）如果time2等于time3，否则time1等于假（0）。

你可能意思是(time1 == time2 && time1 == time3)。

所有其他比较都有类似的问题。每个二进制比较结果都是一个简单的布尔值。你不能像你在演讲中那样加入比较。

谢谢md5i，说实话，你是救命恩人。我很欣赏帮助以及评论，我现在正在大学读C++，所以仍然有很多我不知道。 –
