I stopped using Code::Blocks IDE in my local computer recently due to some issue in compilation and debugging. I mostly use Ideone.com online compiler presently. I use the Secret option by default, which should make my code available only to those whom I choose to share the link. I also use the Custom Invocation option in Codeforces sometimes.
My question is: Should I trust that the Secret option in Ideone.com is secure enough to make sure that no one can get the code without permission? If not, what would be the most reliable secure online C++ compiler that you recommend?
Thanks in advance for sharing your knowledge and experience.
