@swastijain132005 Nice work! I found a couple of issues that need attention:

1. When adding a task, an empty title is accepted. Please validate the title and reject empty input (or show an error message) before pushing the task into the list.
2. Non-numeric input (e.g., letters or strings) for menu choices and task indexes causes the program to enter a failed input state. Please add input validation (check cin.fail()), clear the stream with cin.clear() and cin.ignore(...), and prompt the user again.
