Task Management System

A console-based Task Management System written in C, built as part of the COMP2421 Data Structures course at Birzeit University.

What it does

• Load tasks from a file (tasks.txt)
• Add, delete, and search for tasks
• Mark tasks as performed (removes from main list)
• Undo the last performed task (restores it to the list)
• View unperformed and performed tasks
• Generate a summary report saved to Report.txt

Data Structures Used

• Linked List — stores all unperformed tasks
• Stack — tracks performed tasks for undo functionality
• Queue — manages undone tasks placed back at end of list

Make sure tasks.txt is in the same folder before running.
