我只是用c ++编程，突然之间所有的“cout”和“cin”都是错误和“不明确”。包括系统。
我不知道为什么会这样。一切都很好，我正在编写相同的程序大约2个小时，只是......发生了。
修改
我仍然可以毫无错误地运行该程序，但它们在文本上显示为错误，红色涂鸦线。发生了什么事？
我正在使用Visual Studio 2013 IDE，无论它是什么。

这种事情不仅仅是神奇地发生在它自己身上;你换了东西！在行业中，我们使用版本控制来制作常规保存点，因此当出现问题时，我们可以追溯我们所做的导致该问题的具体更改。
由于你还没有这样做，我们只能猜测。在Visual Studio中，Intellisense（为您提供自动完成下拉菜单和那些波浪形的红线的技术）与发动机罩下的实际C ++编译器分开工作，有时会让事情有点不对。
在这种情况下，我会问你为什么同时包含cstdlib和stdlib.h;你应该只使用其中一个，我推荐前者。它们基本上是相同的头，一个C头，但cstdlib将它们放在命名空间std中，以便“C ++ - ise”它们。从理论上讲，包括两者都不会发生冲突，但是，这就是微软我们所说的。他们的C ++工具链有时会留下一些不足之处。任何时候Intellisense不同意编译器都必须被视为一个错误，无论你怎么看待它！
无论如何，您使用using namespace std（我将来推荐反对）意味着来自std::system的{{1}}现在与{{1}冲突来自cstdlib。我无法解释system和stdlib.h发生了什么。
尝试删除std::cout，看看会发生什么。
如果您的程序构建成功，那么您不必过于担心这一点，但我可以想象当您在IDE中工作时，误报是令人讨厌的。
