- True/False 6. Polymorphism literally means "many changes."class implementation file -- Rectangle.cpp class Rectangle { #include #include "Rectangle.h" using namespace std; private: double width; double length; public: void setWidth (double); void setLength (double) ; double getWidth() const; double getLength() const; double getArea () const; } ; // set the width of the rectangle void Rectangle::setWidth (double w) { width = w; } // set the length of the rectangle void Rectangle::setLength (double l) { length l; //get the width of the rectangle double Rectangle::getWidth() const { return width; // more member functions hereC++ Code for a QueueThe program should features a Queue class with insert(), remove(), peek(),isFull(), isEmpty(), and size() member functions.The main() program creates a queue of five cells, inserts four items, removes threeitems, and inserts four more. The sixth insertion invokes the wraparound feature. All the items are then removed and displayed. The output looks like this:40 50 60 70 80
- class IndexItem { public: virtual int count() = 0; virtual void display()= 0; };class Book : public IndexItem { private: string title; string author; public: Book(string title, string author): title(title), author(author){} virtual int count(){ return 1; } virtual void display(){ /* YOU DO NOT NEED TO IMPLEMENT THIS FUNCTION */ } };class Category: public IndexItem { private: /* fill in the private member variables for the Category class below */ ? int count; public: Category(string name, string code): name(name), code(code){} /* Implement the count function below. Consider the use of the function as depicted in main() */ ? /* Implement the add function which fills the category with contents below. Consider the use of the function as depicted in main() */ ? virtualvoiddisplay(){ /* YOU DO NOT NEED TO IMPLEMENT THIS FUNCTION */ } };class Container {private int val1=1;private void printValue(){final int val2=2;class Containee{public void f(){System.out.println(String.format("Values are: %d and %d."),val1);}}}public static void main(String[] args) {(new Container()).printValue();}} a.The above does not compile because the method f() requires an instance of class Container b.The above does not compile because the class definition in done within the body of the function c.The above code complies with no errors, but does not produce any ouput d.The above code does not compile because the methodf() cannot access the variable val11. Goals and Overview The goal of this assignment is to practice creating a hash table. This assignment also has an alternative, described in Section 5. A hash table stores values into a table (meaning an array) at a position determined by a hash function. 2. Hash Function and Values Every Java object has a method int hashCode() which returns an int suitable for use in a hash table. Most classes use the hashCode method they inherit from object, but classes such as string define their own hashCode method, overriding the one in object. For this assignments, your hash table stores values of type public class HashKeyValue { K key; V value; } 3. Hash Table using Chained Hashing Create a hash table class (called HashTable211.java) satisfying the following interface: public interface HashInterface { void add(K key, V value); // always succeeds as long as there is enough memory V find (K key); // returns null if there is no such key } Internally, your hash table is defined as a private…
- Problem You want to implement a custom class that mimics the behavior of a common built-in container type, such as a list or dictionary. However, you're not entirely sure what methods need to be implemented to do it.C++ Programming Requirments: Please submit just one file for the classes and main to test the classes. Just create the classes before main and submit only one cpp file. Do not create separate header files. Please note: the deleteNode needs to initialize the *nodePtr and the *previousNode. The code to do this can be copied from here:ListNode *nodePtr, *previousNode = nullptr; Part 1: Your own Linked ListDesign your own linked list class to hold a series of integers. The class should have member functions for appending, inserting, and deleting nodes. Don't forget to add a destructor that destroys the list. Demonstrate the class with a driver program.Part 2: List PrintModify the linked list class you created in part 1 to add a print member function. The function should display all the values in the linked list. Test the class by starting with an empty list, adding some elements, and then printing the resulting list out.Fix the errors in the Customer class and the Program. #include <iostream>#include <fstream>#include <string>using namespace std; class Customer {// Constructorvoid Customer(string name, string address) : cust_name(name), cust_address(address){acct_number = this.getNextAcctNumber();} // Accessor to get the account numberconst int getAcctNumber() { return acct_number; } // Accessor to get the customer namestring getCustName(} const { return cust_name; } // Accessor to get the customer addressstring getCustAddress() const { return cust_address; } // Set a customer name and addressstatic void set(string name, string address); // Set a customer addressvoid setAddress(string cust_address) { cust_address = cust_address; } // Get the next account number for the next customer.static const unsigned long getNextAcctNumber() { ++nextAcctNum; } // input operatorfriend Customer operator>> (istream& ins, Customer cust); // output operatorfriend void operator<<…
- void getVectorSize(int& size); void readData(vector<Highscore>& scores); void sortData(vector<Highscore>& scores); vector<Highscore>::iterator findLocationOfLargest( const vector<Highscore>::iterator startingLocation, const vector<Highscore>::iterator endingLocation); void displayData(const vector<Highscore>& scores); The size parameter from the given code won't be needed now, since a vector knows its own size. Notice that the findLocationOfLargest() function does not need the vector itself as a parameter, since you can access the vector using the provided iterator parameters. The name field in the struct must still be a c-string The focus of this assignment is to use iterators. You must use iterators wherever possible to access the vector. As a result, you must not use square brackets, the push_back() function, the at() function, etc. Also, the word "index" shouldn't appear in your code anywhere. You won't get full credit if…code rectangel #include <iostream> using namespace std; class Rectangle{ private: double width; double length; static int numberOfObjects; public: Rectangle(); Rectangle(double , double); ~Rectangle(){cout<<"Destructor called "<<endl;} static void printNumberOfObjects(){ cout<<"number of objects: "<<endl;} void setDimention(double, double); double getWidth(); double getLength(); double getArea(); void printRectangle() const ; double getPerimeter(); }; int Rectangle::numberOfObjects=0; Rectangle::Rectangle(){ /*width = 0; length = 0;*/ cout<<"Default constructor called"<<endl; setDimention(0,0); numberOfObjects++; } Rectangle::Rectangle(double w, double l){ /* if(w>=0)// validation on the input width= w; else width=0; if(l>=0) length = l; else length= 0;*/ cout<<"constructor with parameters called"<<endl; setDimention(w,l); numberOfObjects++; } void Rectangle::setDimention(double W, double L){ if(W>=0)// validation on the…
