I need a C/C++ code emulator a bit more advanced than repl.it etc.

I need a C/C++ code emulator a bit more advanced than [login to view URL] etc. - It will be for both C and C++ - Keywords should be distinguished with color - People will be able to save their codes to download, and see the project results immediately - It will be running for our websites, iOS apps and Android apps after the users are logged in - The rest will be explained after being agreed. The simulator will work both online and on mobile platforms. Did you check [login to view URL] ? Please, check that out and let me know if you can make something which allows people to code C and C++ online (from website) and on mobile (on iOS and Android). People should be able to create their own account, write/change/download their codes under their profiles. In some cases, the sample codes can be loaded from our end if the user purchases our other related products. The application will be paid or free. Free and paid versions will provide different features. Those features will be allowed by a configurator. That configurator will be managed by our end. The features will be listed on the configurator, user types can be created by us and plans and payment related features can be managed by us. For the payment and legal notice we need a confirmation. We also need to confirm if the user is a human. if you confirm that you are able to complete these tasks, other details about the project will be provided . Thanks
