Part 3- Write the following code, run it, fix it and describe what it does.

// ConsoleApplication3FactoryPizzaExample.cpp : This file contains the 'main' function. Program execution begins and ends there. // // Factory Pattern // * Add code for a 4th pizza type: Cheese // * Modify the pizza information function, so it prints the pizza name // * Comment each function - Explaining what it does // * Explain why this is a factory pattern
