Read this story and calculate/print the x total eggs collected between Monday and Wednesday:
Mang Jose’s chickens always lay eggsPerChicken eggs precisely at noon, which he collects that day.
• On Monday, Mang Jose has chickenCount chickens.
• On Tuesday morning, Mang Jose gains 1 chicken.
• On Wednesday morning, a wild beast eats half the chickens!
For Example:
• If Mang Jose starts with eggsPerChicken = 5 and chickenCount = 3, he must then collect a total of 45
eggs
• If Mang Jose starts with eggsPerChicken = 4 and chickenCount = 8, he must then collect a total of 84
eggs
Develop a C++ program that calculates how many eggs will Mang Jose collects based on user input.

You’ve been asked to write a small menu driven inventory management system for a small convenient store. Item ID – unsigned long Item name – string Item cost – float Quantity - int
Following are the list of administrative functionalities your application shall support:
1.Add new item to the inventory. This function will be used to add a single new item into the inventory management system.
2.Print all item information in the store - This function will be used to display all items in the inventory. When this option is selected system shall print Item ID, Item name, Item cost and quantity. 3.Find item by ID – This function will be used to search item using an ID. If item exist print item information. If not display an error indicating item not found.
4.Find item by name – This function will be used to search item using name. If item exist print item information. If not display an error indicating item not found.
Write a menu driven application in
C++.
