What's wrong if I use string as "c::\\"

Question

Hi

Refer code below:
It works fine. If I change the file name to c:\ (uncomment the commented line), it displays wiered results.

What's wrong with this code ?

Answer 1

Sololearn compilers run on linux, so windows \\ would not be recognized.

oh, I see what you mean. the second string seems to be parsed into ..\Playground\ when used in cout...

not sure if it's a Sololearn thing.

But here is my workaround if you just want the string to be displayed:
(you shouldn't actually use raw string as path, though)

Answer 3

Sololearn deliberately put that into their batch run script some years back. They replace file paths in the output file stream with ..\Playground\. I think it was an effort to quell hacking their server. It's a fun challenge to find workarounds. I will leave it as an exercise for the reader.

Answer 4

I am just using it as a string and not used as actual path of file system.

It is a raw string for me named as file name. Is it something string has this restrictions imposed ?
