Task Manager

A C-based CLI Task Manager that demonstrates core data structure design and pointer-level implementation. The project uses a circular linked-list queue for scheduling plus stack-backed undo/redo histories for reversible task actions.

Overview

• Language: C
• Environment: VS Code with MSYS2
• Core architecture:
  • 1 circular linked-list queue for task scheduling
  • 2 stacks for undo/redo history management

Main Functions

• Add, remove, and view tasks
• Undo/redo recent task-state changes
• View undo and redo stacks
• Execute custom queue and stack operations with dynamic memory allocation

Technical Highlights

• Implemented custom enqueue/dequeue queue operations
• Implemented stack push/pop operations with O(1) retrieval behavior
• Applied dynamic memory allocation and pointer manipulation across queue/stack nodes

Resume-Ready XYZ Bullets

• Increased task scheduling reliability by building a C CLI task manager around 1 circular linked-list queue, implementing custom enqueue/dequeue operations to process task actions in deterministic order across the demo workflow.
• Improved recovery speed and usability by implementing 2 stack-backed histories (undo/redo) with O(1) push/pop retrieval, enabling immediate rollback/reapply of task-state changes during command execution.
• Strengthened low-level implementation quality by developing and integrating 3 custom data-structure operations (enqueue, dequeue, push/pop) with dynamic memory allocation and pointer manipulation, reducing edge-case failures during interactive task updates.
