What should be noted when getting the current path in C++?

When obtaining the current path in C++, it is important to consider the following points:

1. To retrieve the current path, you can use OS-specific functions or libraries. For example, on Windows, you can use the GetCurrentDirectory function, and on Linux, you can use the getcwd function.
2. When using functions or libraries related to the operating system to obtain the current path, it is important to ensure that the program’s execution path is reliable. You can use relative or absolute paths to guarantee that the obtained path is correct.
3. When using the C++ standard library, you can utilize the filesystem module in the boost library to access the current path, which enables cross-platform usage and provides additional functionalities.
4. Ensure that the program has sufficient permissions to access the current path when retrieving the current path, otherwise you may encounter insufficient permission errors.
5. After obtaining the current path, you can use a path joining function to construct file paths, making it easier to manipulate files and directories.
