Building a To-Do List Application in C++

In this guide, we will create a simple console-based To-Do List Application in C++. The application will allow users to add tasks, mark tasks as completed, view the list of tasks, and remove tasks. Here's a step-by-step outline and sample code to help you get started:

Step 1: Define Task Structure

Define a structure to represent a task, including its description and completion status:

#include <iostream>
#include <vector>
using namespace std;
struct Task {
    string description;
    bool completed;
};
    

Step 2: Create a Vector to Store Tasks

Create a vector to store the list of tasks:

vector<Task> taskList;
    

Step 3: Implement Menu and User Interface

Create a menu for users to interact with the application. Provide options to add, view, mark as complete, and remove tasks:

int main() {
    char choice;
    do {
        cout << "To-Do List Application" << endl;
        cout << "1. Add Task" << endl;
        cout << "2. View Tasks" << endl;
        cout << "3. Mark as Complete" << endl;
        cout << "4. Remove Task" << endl;
        cout << "5. Exit" << endl;
        cout << "Enter your choice: ";
        cin >> choice;
        switch (choice) {
            case '1':
                // Implement task addition
                break;
            case '2':
                // Implement task viewing
                break;
            case '3':
                // Implement marking a task as complete
                break;
            case '4':
                // Implement task removal
                break;
            case '5':
                cout << "Exiting application." << endl;
                break;
            default:
                cout << "Invalid choice. Please try again." << endl;
        }
    } while (choice != '5');
    return 0;
}
    

Step 4: Implement Task Operations

Implement the logic for adding, viewing, marking as complete, and removing tasks within the respective cases of the switch statement.

Step 5: Build and Run

Compile your C++ program and run the application. You can interact with the To-Do List using the provided menu options.

This is a basic outline to get you started on building a To-Do List Application in C++. You can expand and enhance the application by adding features such as task persistence (saving to a file), due dates, and prioritization.
