Write a C++ program to create a simple shopping cart application. The program should allow users to add items to their cart, specify the quantity of each item, and calculate the total cost of their purchase. The program should have the following features: 1. Item Database: • Create an array or a data structure to store information about at least 5 different items available for purchase. • Each item should have a name, price, and a unique identifier. 2. Adding Items to Cart: Prompt the user to add items to their cart by entering the item's unique identifier and the quantity they want to purchase. • Allow the user to add multiple items to their cart. 3. Calculate Total Cost: Calculate the total cost of the items in the user's cart, considering the quantity of each item. Display the total cost to the user. · . • 4. Display Receipt: Display a receipt showing the details of each item in the user's cart, including the item name, quantity, price per unit, and the total cost for each item. 5. Include Comments: Use multiple-line comments to identify the owners (who wrote it) and their IDs. Explain the purpose of the program and the input and output of the code. • Use single-line comments to explain complicated or confusing statements and justify your reasoning (include at least 3 comments). 6. Code Readability: • Use white spaces such as indentation, spaces, and blanks for better readability. Choose self-documenting variable names. . . 7. User Interaction: • Ensure that the program interacts with the user by providing clear instructions and prompting for input. • Conclude the program with a message that expresses gratitude or provides some interesting information related to shopping.

Please use C# for this. Thank you soo much!

Data structure & Alogrithums java program A system of caves is a group of connected undergrounds tunnels. Design an ADT for a cave and cave system. An archaelogist should be able to add a newly discovered cave to a cave system. He/she can enter this system through only one cave and exit the system only through a different cave. Duplicate caves - based on GPS coordinates - are not permitted. Archaelogoist should also be able to list the caves in a given cave system.

Attention>>>>>>>>> project should written in C languages In the project, a student affairs information system simulation is requested to be made using structures (“struct”), linked lists (“linked list”) and files (“file”). According to this; a) Create a structure called a course. The members of this structure are code, name, instructor, term (can take Spring or Fall values), year, and a course pointer. Functions with prototype void insertCourse(CourseNodePtr* cr, CourseNodePtr* inscr, char* code), char* deleteCourse(CourseNodePtr* cr, CourseNodePtr* inscr, char* code) that will operate on course data structure elements, since the courses taken by the students are to be kept with a linked list. write. While writing the insertCourse() function, prevent the same student from taking the same course more than once. b) Create a structure called student. Let the members of this structure be id, name, surname, department, class (can take B.Sc., M.Sc., Ph.D.),…
