how to make user enter the path of the xml file in tinyxml2

Question

How i can make the user enter the path of the xml file to be saved?

I want the user to enter something like "c:\test.xml" and the xml file is generated by that name and location.

I tried

 string PathName;
 cin >> PathName;
XMLDocument doc;
doc.SaveFile(PathName);

but it gives me the error

 no instance of overloaded function matches the argument list

I know its such a simple question but somehow I am stuck, sorry

Why not read the project's documentation to find out how to use it? — Asteroids With Wings, Jun 04 '20 at 17:51
@Asteroids With Wings, I want to create a new xml file based on the inserted path name — Alice, Jun 04 '20 at 17:52
That doesn't explain why you're not using the project's documentation. — Asteroids With Wings, Jun 04 '20 at 17:55
@Asteroids With Wings, if I know how to use it I would not ask? I have been following it correctly but got stuck at this point — Alice, Jun 04 '20 at 18:02

I think your error is telling the parameter type doesn't match an overload. Try this instead:

auto result = doc.SaveFile(PathName.c_str());

Edited to include result from the function - if it fails it should give you an error code. Quoting the docs:

Save the XML file to disk. Returns XML_SUCCESS (0) on success, or an errorID.

now the program works but it does not save the file by the inserted name and path – Alice Jun 04 '20 at 17:42
You need to provide more information then. What is the filename/path you are passing in? How are you running the program? – castro Jun 04 '20 at 18:02
I want the user to enter the path to where the file should locate and the name for it. For example the input is "c:\test.xml" the program saves the file in c with the name test. I am using VS2019 – Alice Jun 04 '20 at 18:05
If you are trying to save to the C drive (as opposed to a user directory) make sure you are running VS with admin privileges – castro Jun 04 '20 at 18:06
I am running it with admin privileges, also I am trying to save it to anywhere really, it depends on the user – Alice Jun 04 '20 at 18:09
Try checking the return from the function - edited my answer with more info. – castro Jun 04 '20 at 18:44
Btw I have just tried this myself and it works. If there is more to your code, please share it. Also consider hard-coding your filename to remove the possibility of user input error. – castro Jun 04 '20 at 19:14
