Stack Overflow is a web-based knowledge-sharing platform that has answers for all your program-related doubts. You can filter the answers to your question based on upvotes and downvotes. It is mostly used by IT professionals and developers. If you are a frequent user of Stack Overflow or if you are using Stack Overflow for a prolonged time, your eyes may strain due to the bright light, and you might face difficulty in reading.
