i highly recommended u to use "solo learn " android app. It is best to learn various programming languages in your smart phone. Aslo it have an online compiler so you can test and see how your code is working. The app needs internet connection for the first time to sign up and download the course that u need. But after that u can use it offline. Some good futures of this app are -it gives u valid certificate when u finish certain programming courses -u can match with other users of this app -u can see ur rank from the world and from ur country 👉So i recommend u to use this app
