I implemented a task manager that can help you keep your tasks, delete some and even see the saved tasks. The tasks are saved in a file so that they don't disappear after the user closes the program.
It is fully implemented in C++. I made it so that the code is really easy to understand for someone with some knowledge of C++ and STL. For the time being it only works in the Terminal. But there will be an app version done with Qt in the near future.
Hope you enjoy!
