C++ Command Line To-Do List

A console based task management application implemented in C++. This program demonstrates core computer science concepts by using a custom singly-linked list to store, manipulate, and display user tasks.

Features

• Add Tasks: Insert a new task at any specific position in the list.
• Delete Tasks: Remove a task from a specific position.
• View Count: Print the current number of tasks.
• Print List: Display all tasks in order from first to last.
• Reverse Print: Display all tasks in reverse order using recursion.
• Input Validation: Handles invalid menu choices and positional input.

How to Compile and Run

1. Ensure you have a C++ compiler (like g++) installed.
2. Navigate to the project directory in your terminal.
3. Compile the source code:

   g++ -o todo main.cpp

4. Run the executable:

   ./todo

Code Structure

• main.cpp: Contains all source code.
• taskNode Struct: Represents a node in the linked list, holding a task string and a pointer to the next node.
• taskList Struct: Manages the linked list, holding a pointer to the head node and an integer tracking the task count.
• The program uses iterative traversal for most functions and recursion specifically for printing the list in reverse.

Concepts Demonstrated

• Data Structures (Singly-Linked List Implementation)
• Pointers and Memory Management (new/delete)
• Recursion
• User Input/Output Handling

Future Enhancements

• Persistence: Save and load the task list from a file.
• A graphical user interface (GUI) using a framework like Qt.
• Additional task properties (due dates, priorities, categories).
