Todo List Application in C++

This is a command-line-based Todo List application written in C++. It allows you to create, manage, and track tasks with features such as priority setting, due dates, and filtering.

Features

Add Tasks:

Add a task with a description, due date, and priority level.

View Tasks:

Display all tasks or only completed tasks.

Update Tasks:

Modify the description, due date, and priority of existing tasks.

Delete Tasks:

Remove tasks by ID.

Mark as Completed:

Mark tasks as completed by ID.

Search Tasks:

Find tasks by ID.

Filter Tasks:

Filter tasks by priority or due date.

Count Tasks:

Display the total number of tasks, completed tasks, and incomplete tasks.

Data Persistence:

Saves tasks to a file (todo.txt) and reloads them when the program is restarted.

How to Run

Clone the repository:

git clone https://github.com/sandeep079/TodoListApp.git cd TodoListApp

Compile the program:

g++ -o todo_list_app todo_list_app.cpp

Run the program:

./todo_list_app

Note: The program uses a text file (todo.txt) to store tasks. Ensure that the file exists in the same directory as the executable, or it will be created automatically on first run.

Requirements

A C++ compiler (e.g., g++ or clang++)
Operating System: This program is designed for use on Windows (due to the use of system("cls")), but it can be modified for other systems by handling console clearing differently.

File Structure

TodoListApp/ │ ├── todo_list_app.cpp # Main source code ├── todo.txt # File where tasks are stored (auto-generated) ├── README.md # Project documentation └── .gitignore # Git ignore file (optional)

Future Enhancements

Add the ability to search for tasks by description or due date.
Improve date validation to include checks for leap years, month length, etc.
Provide better cross-platform support for clearing the console.
Implement a GUI version.
