Why this code works perfectly on codeblocks but doesn't work here?

Question

Hello guys....
I am quite new to sololearn and trying to learn C++
So after going through some tutorials I decided to write a code using classes...

http://www.sololearn.com/app/sololearn/playground/cLWDFemppaLN/

This is the code I wrote...but I can't make it work on sololearn app properly but works perfectly on codeblocks...Want to know why?

And also seeking some suggestions on how to improve this code...

thanks in advance

Because code blocks isn't real coding. You gotta understand the stuff here.
