程序已停止工作

Question

我在C++中编译的程序有问题。我写了一个程序，当我键入程序的东西我立即收到此消息：

以下是译文：

程序已停止工作

一个问题引起该程序正常工作。 Windows将关闭该程序并通知您是否有解决方案。

这里是我的源代码：

我真的很感激帮助如何解决这个错误。

的意见是正确的。你应该学会使用循环。

说了这么多，这个问题是更可能使用的是未初始化的变量。看到这个：

U78=I678*R78 

I678的值是未初始化的，但你用它来计算U78。我的Visual Studio还报道这些变量初始化之前被使用：

1>warning C4700: uninitialized local variable 'R78' used 1>warning C4700: uninitialized local variable 'U12345' used 1>warning C4700: uninitialized local variable 'U123' used 1>warning C4700: uninitialized local variable 'I2' used 1>warning C4700: uninitialized local variable 'U4' used 1>warning C4700: uninitialized local variable 'R4' used 1>warning C4700: uninitialized local variable 'I9' used 1>warning C4700: uninitialized local variable 'R9' used

你在做师行使用这些直接或间接的，因此，如果他们是初始化时，程序会表现出不确定的行为。所以初始化你的变量，更好地设置你的代码的格式，以便一行代码的长度不是很多，并开始使用循环。
