【中文标题】我的程序可以在 Visual Studio 中运行，但不能在其他 IDE 示例 AWS Cloud 9 中运行

【英文标题】：My programs works in Visual Studio but not in other IDE example AWS Cloud 9

【问题描述】：

我在 Visual Studio 中创建了我的程序，它运行良好，输入/输出等都是正确的。当我在 AWS Cloud 9 或 Mirmir 中运行它时，我收到相同的错误消息，这是什么意思？我应该如何修改它以在 AWS 中工作？我认为 C++ 代码适用于所有支持 C++ 的 IDE。错误是：

在构造函数“Departments::Departments(int, char*, char*)”中： 错误：未在此范围内声明“strcpy_s” strcpy_s（部门名称，部门名称）； ^

在构造函数'Employee::Employee(int, char*, double, double, int)'中： 错误：未在此范围内声明“strcpy_s” strcpy_s(emploeename, nameOfTheEmployee);

【问题讨论】：

您可以使用strcpy，但在Visual Studio 中定义_CRT_SECURE_NO_WARNINGS

【参考方案1】：

您的 Visual Studio IDE 可能已经为您加载了其他 IDE 没有的库。看起来strcpy 是 库的一部分。您需要#include <cstring> 才能使用它。

【参考方案2】：

Visual Studio 在 Windows 上运行，而 Cloud9 在 linux 上运行。他们使用不同的编译器和不同的标准库。
