and if this solves your problem you can accept my answer 
You are absolutely right. to_string() doesn’t work on code::blocks

It doesn’t work in codebloacks
I have version 6
Basic way of not getting the error is
use command:
g++ -std=c++0x File.cpp
This will remove all sort of errors for to_string or stoi(), or for other functions
I had the same problem, and even changing the flag to std=c++0x it don’t work. I copy the file that you post and it is working!!, thanks a lot.
I am also facing the same error. It says "to_string was not declared in this scope ". Can any one can give the solution for it in codeblocks
