Explanation
- Class
Task:- Purpose: Represents a single task within a project.
- Attributes:
name: Name of the task.assignedTo: Person responsible for the task.priority: Priority level of the task (e.g., 1-10).isComplete: Status indicating whether the task is complete.
- Methods:
markComplete(): Marks the task as complete.print(): Prints task details in a formatted manner.
- Class
Project:- Purpose: Manages a collection of tasks.
- Attributes:
tasks: Vector ofTaskobjects.
- Methods:
addTask(): Adds a new task to the project.markTaskComplete(): Marks a specific task as complete by its index.printTasks(): Prints the details of all tasks.
- Main Function:
- Setup: Creates an instance of
Project. - Menu: Provides a menu for the user to add tasks, mark tasks as complete, print tasks, or exit the program.
- Input Handling: Reads user input to manage tasks and interact with the project management system.
