Task Management System

Description

This is a simple console-based Task Management System implemented in C++. The program allows users to create, update, remove, and display tasks categorized into four groups:

1. My Day
2. Assigned To Me
3. Important
4. Planned

Each task consists of a title, category, deadline, note, and priority level (High, Medium, or Low).

Features

• Add Tasks: Users can add new tasks by providing the required details.
• Remove Tasks: Users can delete existing tasks based on their title.
• Update Tasks: Users can modify task attributes such as title, category, deadline, note, or priority.
• Display Tasks: Users can view tasks based on categories or display all tasks in the database.
• Persistent Storage: Tasks are stored in text files (MyDay.txt, AssignedToMe.txt, Important.txt, Planned.txt) for data persistence.

Compilation and Execution

Compilation:

To compile the program, use the following command in a terminal:

g++ -o TaskManager main.cpp

Execution:

Run the compiled executable:

./TaskManager

Usage Instructions

1. Upon starting the program, you will be prompted to select a task category.
2. Inside a category, you can choose to Add, Remove, Display, or Update tasks.
3. When adding a task, follow the required format:
   • Deadline Format: mm/dd/yyyy
   • Priority: 1 for High, 2 for Medium, 3 for Low`
4. To update or remove a task, you need to provide the correct task title.
5. Selecting Exit will terminate the program, saving changes to respective files.

File Storage Format

Each task is stored in a category-based text file in the format:

TaskTitle;TaskCategory;TaskDeadline;TaskNote;TaskPriority

Example (MyDay.txt):

Complete Project;My Day;04/10/2025;Work on the final project submission;1 Buy Groceries;My Day;04/12/2025;Buy milk, eggs, and bread;3

Error Handling

• Invalid inputs are handled to prevent crashes.
• Users are prompted to re-enter values if they input incorrect formats.
• The system prevents duplicate task titles in a category.

Dependencies

• Standard C++ libraries (iostream, fstream, string, vector, sstream, regex, etc.)
• No external dependencies required.

Possible Future Enhancements

• Implement a graphical user interface (GUI) for better user experience.
• Support for recurring tasks and notifications.
• Improve search functionality within tasks.
