2) The class definition of a Doubly Linked List class is given below, It contains an attribute called top that represents the top of a doubly linked list, It abo includes one constructor, a print method that should print the elements of the list in reverse order. It also includes another method that shoukd add a note on the top of the doubly linked list. The constructor is implemented. Your job is to implement the printReverse() and insertOnThe Top(O methods. Note: Please do the implementation on the next page #include using namespace std; I1- class Node; typedef Node* NodePtr; class Node public: int number; NodePtr next; NodePtr prev; Node(){number 0; next prev NULL:} Node(int n) {number n; next-prev NULL;} 3B 11-- class DoubleLL private: NodePtr top; public: DoubleLL() (top NULL;} void printReverse(%: bool insertOnTheTop (int n); }3; 11-

Need help with C++ Question.

In C++, there is a specialized kind of variable known as a pointer variable that you may utilize. Do you have a knowledge of how to put it to use in various situations?

Please I need to answers these questions in C++. Thank you. Question: Does the if-else if structure offer any advantages over nested if statements? Choose the correct answer from below: A. It helps keep the code understandable and readable on the screen or on paper B. It does away with the need of a trailing else C. It can handle logic that nested if statements cannot handle D. Neither has an advantage over the other E. The text did not discuss this topic   Question: What is the purpose of a trailing else in an if-else if ladder structure? Choose the correct answer from below: A. It handles the "none of the above" situation in the problem B. Two of the other answers are correct C. It is often used to catch errors D. It deals with the most complex boolean expression  E. It is the only part of the ladder that is not optional

Pls make a code for this on c++ and make sure it is 100% correct. i wastred 4 questoins on this  and they all are not correct.  Write the code as described in the questions below. Submit your code electronically in the box at the bottom. You may only use Java, C# or C++. The economy is defined using a 2-dimensional data structure:   A “payday” will be considered to be any region of $ values where all cells in the region are connected either vertically or horizontally. For example, the following illustrates a matrix with 5 rows and 8 columns containing three objects. $’s and P are used in the diagram to represent the two types of values: PPPP$PPPPPP$$PPPPP$$PPP$PP$PPPP$P$PPP$$$ a)   Write a program to read in the data from the text file and store it into a data structure. Your program should output it to the screen after it has read in the file. (If you can’t get this to work hard-code the above example and continue to part b). Here is a sample text file (containing the above data):…
