程序已停止工作

Question

我在使用 C++ 编译程序时遇到问题。我编写了一个程序，当我在程序中输入内容时，我会立即收到以下消息：

翻译如下：

程序已停止工作

一个问题导致程序正常工作。如果有可用的解决方案，Windows 将关闭该程序并通知您。

这是我的源代码：

#include <iostream>
#include <fstream>

非常感谢有关如何解决此错误的帮助。

cmets 是真的。你应该学会使用循环。

话虽如此，问题很可能是您使用了未初始化的变量。看到这个：

U78=I678*R78

I678 的值未初始化，但您正在使用它来计算 U78。我的 Visual Studio 还会报告这些变量在初始化之前被使用：

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

您在执行除法的行中直接或间接使用这些，因此如果它们未初始化，程序将表现出未定义的行为。所以初始化你的变量，更好地格式化你的代码，这样一行的长度就不会是无数个字符，然后开始使用循环。
