4) How many syntax errors in the following code? Assume all libraries areincluding#include using namespace std;class ShapeType {protected:double length, width;void setDimension (double L, double w) { length = L; width = w; }void print() {};;};class rectangleType :protected ShapeType{private:public:};double length, width;rectangleType() { length = 0; width = 0; }rectangleType(double L, double w) {setDimension (L, w); }void setDimension (double L, double w) { length = L; width = w; }double getLength() { return length; }double getwidth() { return width; }double area() { return length width; }double perimeter() { return 2* (length + width); }void print() {ShapeType: :print();}Your answer:5) How many true statement(s) among the following?CommA. Templates in C++ are commonly used to repeat code by generating aset of classes and functionsB. Friend functions are member functions that have the right to accesspublic and protected member functions.C. The process of overloading an operating in C++ MUST include writinga functionD. Overloading an operator is commonly used to change its precedenceE. It is possible to create new operators in C++F. We can override built-in type operators in C++6) How many false statement(s) among the following?A. Set in STL is an associate container for storing unique values andallows rapid lookup101101010101011B. Keys in STL's map are uniqueC. We give the highest priority to the first element in the STL's priorityqueueD. Recursion in C++ allows functions to be calling themselves directly orindirectly and provide an elegant way to define functionsE. Memory addresses store integers that can point other integersF. Overloading the [] operator requires that the function is a member ofthe class

Create parent class Shapes with protected parameters width and height and function printarea() and a virtual function cal_area(). Create two sub classes Rectangle and Sqaure. In main() create 2 pointers of Shapes and assign Rectangle and Square to it. Call printarea function with the pointers. Note: use OOP C++
Using classes, design an online address book to keep track of the names, addresses, phone numbers, and dates of birth of family members, close friends, and certain business associates. Your program should be able to handle a maximum of 500 entries. Define a class addressType that can store a street address, city, state, and ZIP code. Use the appropriate functions to print and store the address. Also, use constructors to automatically initialize the member variables. Define a class extPersonType using the class personType (as defined in Example 10-10, Chapter 10), the class dateType (as designed in this chapters Programming Exercise 2), and the class addressType. Add a member variable to this class to classify the person as a family member, friend, or business associate. Also, add a member variable to store the phone number. Add (or override) the functions to print and store the appropriate information. Use constructors to automatically initialize the member variables. Define the class addressBookType using the previously defined classes. An object of the type addressBookType should be able to process a maximum of 500 entries. The program should perform the following operations: Load the data into the address book from a disk. Sort the address book by last name. Search for a person by last name. Print the address, phone number, and date of birth (if it exists) of a given person. Print the names of the people whose birthdays are in a given month. Print the names of all the people between two last names. Depending on the users request, print the names of all family members, friends, or business associates.
Please pay attention to the required data types in the description. Thetuple, list and vector classes and their objects are not allowed to be used. 1. Define a new C++ class named “PayStub” that manages pay information: number of hours (integer), hourly pay rate (double). The total payout amount will be calculated based on overtime. Any hour that ismore than 40 hours will be paid at 1.5 pay rate. For example, with the hourly pay rate of $10.0 and if the number of hours is 40, the payout amount will be 400 and if the number of hours is 50 it will be (40 * 10)+ (10 * 15) = 550Please note that because the payout is a calculated value, it should not be part of the data members to make the object as small as possible. The class must provide at least the following two methods:• toString method that returns the string containing all the information about the paystub including the total payout amount. For example, here is the output for different paystubs:40 hours at $10.0 an hourHOURS(40)…
i will upvotes unique answer plzz (Use language OOP in c++) Create a class Student with data members age and marks, both of type integer. Provide a parameterized constructor and a set member function to set the data members. The age should be a positive number between 15 and 40 while the marks should be between 0 and 100. Create a class InvalidRange as exception handler of the Student class. Add two private data members (a string and an integer) to theclass InvalidRange. Provide appropriate constructor and get methods for the data members. The string should store the name of the function throwing the exception while the integer should store the invalid value the user has supplied. The student class should throw an exception if any of its member functions attempts to assign an invalid value to the data members. In the main program, create objects of class student, assign valid/invalid values to the data members and catch the exceptions accordingly. Extend the program to have two…
