Family Tree Builder - DSA

A C++ program to build and visualize a hierarchical family tree. This application enables users to interactively add family members, define parent-child relationships, and visualize the family tree structure. It robustly handles scenarios where users attempt to add a family member to a specified parent who may or may not exist within the tree.

Constraints

• Each individual in the family tree is represented by their name, birthdate, and a list of their children.
• The family tree begins with a single root individual.
• The program should support adding and visualizing multiple generations in the family tree.
• Visualization should use ASCII-based hierarchy representation for clarity.
• The program should provide user-friendly input validation and error messages for invalid operations

Solution Description

1. Define the Individual class with private attributes for name, birthdate, and a vector of children. Include methods for adding a child, getting the name, birthdate, and children.
2. Define the FamilyTree class with a private attribute for the root individual. Include methods for adding a child, visualizing the family tree, and getting the root.
3. In the main function, create an instance of the FamilyTree class with a root name and birthdate.
4. Create a vector of Individual* called individuals and add the root individual to it.
5. Enter a loop to display the main menu and handle user input. Repeat until the user chooses to exit.
6. Inside the loop, display the main menu options:
   • Add Family Member
   • Visualize Family Tree
   • Exit
7. Prompt the user to enter their choice.
8. If the user selects "Add Family Member":
   • Prompt the user for the parent's name, child's name, and child's birthdate.
   • Search for the parent in the individuals vector to find the individual to whom the child will be added.
   • Create a new Individual for the child and add it as a child of the parent.
   • Add the child to the individuals vector.
   • Display a success message.
9. If the user selects "Visualize Family Tree":
   • Call the visualizeTree method on the root individual to display the family tree hierarchy.
10. If the user selects "Exit":
    • Display a goodbye message.
    • Break out of the loop to exit the program.
11. If the user enters an invalid choice, display an error message.
12. Repeat the loop until the user chooses to exit.
