Create a quiz answer sheet checker. That does the following: 1. Posts questions – at least 5- then let the user input answers per question , it can be a multiple choice question, or solving question which will have a number for an answer. 2. After the user inputs their answer, let the program check the answer and display the score of the user.
Constructors(default, parameterized, copy) & destructor
void PrinList(),int search_Element(int X), bool Insert_Element(int X),
int
Insert_Element_at(int X, int pos), int Delete_Element(int X), void is_Empty(), int
Length(), void Print_Reverse_List(), bool Empty_List(),
Also write a driver (main) program to test your code (provide menu for all operations )
Your task is to make a class and perform the following functions
1)void PrinList()
2)int search_Element(int X),
3)void Insert_Element(int X),
void
4)Insert_Element_at(int X, int pos), 5)bool Delete_Element(int X),
6)bool is_Empty(),
7) int
Length(),
8)void Print_Reverse_List(),
9) void Empty_List(),
10)void Copy_List(…)
Note:
1)No global declarations
2)Make copy constructor
3)Make default constructor
4)Make constructor with arguments
5)Test the functions inside main
1)A function insert element at head of list
2)a function insert element at tail of list
3)A function insert element at any position
4)a function delete element at head of list
5)a function delete element at tail of list
6)a function delete element at any position
7) a function to check if list is sorted if not then returns sorted list
8) a function that displays the list
9) a function that reverses the list
Note:
no global declarations
Test the functions inside main

In a library a librarian is stacking the books using their numeric ids. He may push or pop a book from top and want to know which book ids are currently in the stack. Make a class based menu driven program to take size of stack in 1st line and then either of options – pop, push or stop. If pop or stop option is given no numeric value follows but if push is given a numeric value to be pushed is given.
Sample Input:
5 push 3 push 1 push 9 push 11 pop push 4 push 7 pop stop
Output:
Welcome to stacks!
Give one of options: pop, push, stop
Give one of options: pop, push, stop
Give one of options: pop, push, stop
Give one of options: pop, push, stop
Give one of options: pop, push, stop
Element popped: 11
Give one of options: pop, push, stop
Give one of options: pop, push, stop
Give one of options: pop, push, stop
Element popped: 7
Give one of options: pop, push, stop
Stack elements are:
