[Error] 'strcpy_s' was not declared in this scope; did you mean 'strcpy'?

这个错误提示通常是因为你的代码中调用了 `strcpy_s` 函数，但编译器无法找到该函数的声明。`strcpy_s` 是 C11 标准中新增的函数，需要在头文件中包含 `<string.h>` 并定义宏 `_CRT_SECURE_NO_WARNINGS`，否则编译器会认为该函数不安全而报错。如果你的编译器不支持 C11 标准，可以考虑使用 `strcpy` 函数代替。

strcpy_s was not declared in this scope"

这个错误通常表示编译器无法找到函数strcpy_s的声明。这个函数是C++11标准中的函数，用于字符串复制，需要包含头文件<cstring>。如果你在使用该函数时出现了该错误，请确保你已经包含了正确的头文件，并且编译器支持C++11标准。如果还是无法解决问题，可以尝试使用其他字符串复制函数，比如strcpy或者memcpy。

error: ‘strcpy_s’ was not declared in this scope; did you mean ‘strcpy’?

This error message occurs when the `strcpy_s` function is not recognized by the compiler. `strcpy_s` is a secure version of the `strcpy` function, which helps to prevent buffer overflow errors.

To fix this error, you need to include the appropriate header file. On Windows, the `strcpy_s` function is defined in the `string.h` header file. You can add the following line to the top of your code to include this header file:

#include <string.h>

Alternatively, you can replace the `strcpy_s` function with the standard `strcpy` function, which is defined in the `string.h` header file as well. However, note that the `strcpy` function is not as secure as `strcpy_s`, and may lead to buffer overflow errors if used incorrectly.
