++ program to create a list of students with their scores. Use an appropriate data structure and explain the reason for the choice. Demonstrate the difference between a map and a multimap

Something like a data structure that can't be implemented using an array or a link, for instance.Do any potential implementation strategies endanger the building?

Write a c++ program to simulate a coffee shop or a Mcdonald's drive-thru where different customers give an order and they receive a unique ID then you use Queue Data Structure to arrange the order and use a sorting algorithm to sort identical orders so that you can make your entire servicing faster at the end the customer is given a receipt with his order, price, and ID on it. Make sure to use classes.

Write a program using the stack for parenthesis matching. Explain what modifications would be needed to make the parenthesis matching algorithm check expressions with different kinds of parentheses such as (), ] and (}'s. Please write simple C programs to answer the question. Examine your codes with some examples. You should upload your runnable codes + report (single pdf) that explains your codes and results as a single zip file.

implement a c#  program that tests our implementation of the CSet class by creating two sets, performing a union of the two sets, an intersection of the two sets, finding the subset of the two sets, and the difference of the two sets.

implement C# code to create a list of Card objects, add two Card objects to the list, use a loop to flip the cards in the list and print it.

I don't get the "//To be implemented" comments, what am I supposed to do?Also, are the header files and header files implementation different? Like is the linkedList.h different than the linkedList.h (implementation)?

Provide full C++ code Building a playlist (of songs) using a linked list and making some operations such as adding songs, removing songs, shuffling them, etc. (Some parts of this lab will closely follow lab 08 - it is imperative that you complete that lab before working on this project). A Node representing a song has the following data members (similar to struct Node of lab 08, except it doesn't have one member for storing data): string uniqueID  string songName string artistName int songLength Node* nextNodePtr Your code must have the following three files: Playlist.h - Class declaration for a linked list of Nodes (very similar to lab 08 but with some changes to methods, as described below) with following private data members: private:Node* first;Node* last;int size; Playlist.cpp - Class definition main.cpp - main() function Checkpoint A For checkpoint A, you need to build a playlist (of songs) by readings data members of several songs from a file and printing them. Implement…

Could I get an example of a program writen in C that uses qsort() to sort its command line vector argv by the length of the strings? This is part of my first project and I don't understand pointers very well. If you have a video on how it is done that would work too. I looked at the meterial provided to me and I still cant rap my head around it. If this is to big of a question if you could baby step me through how pointers work that would be a great help. Thank you

Please answer in C++ and give explanation LAB 17.1-B Linked List Read the internal documentation for class ItemList carefully. Fill in the missing code in the implementation file, being careful to adhere to the preconditions and postconditions. Compile your program. ------------------------------------------------------------------------------------------------------------------------------- class ItemList { private: struct ListNode { int value; ListNode * next; }; ListNode * head; public: ItemList(); // Post: List is the empty list. bool IsThere(int item) const; // Post: If item is in the list IsThere is // True; False, otherwise. void Insert(int item); // Pre: item is not already in the list. // Post: item is in the list. void Delete(int item); // Pre: item is in the list. // Post: item is no…
