For the following code, which statement is NOT true? class Point { private: double y; double z; public: double x; }; x is available to code that is written outside the class. The name of the class is Point. x. y, and z are called members of the class. z is not available to code that is written outside the class. All of these are true.

Mark the following statements as true or false. The member variables of a class must be of the same type. (1) The member functions of a class must be public. (2) A class can have more than one constructor. (5) A class can have more than one destructor. (5) Both constructors and destructors can have parameters. (5)

Write program in C++ Language The other solutions on chegg were incorrect! Please read carefully! Write a program that defines and tests a class called COP3014. The class resembles aclassroom. It has the following grading scheme:3 quizzes 20 points each 20%Mid term 100 points 30%Final 100 points 50%Based on the total grade of any student for the course, the letter grade of each student can becomputed as follows:Any grade of 90 or more is an A, any grade of 80 or more (but less than 90) is a B, any grade of70 or more (but less than 80) is a C, any grade of 60 or more (but less than 70) is a D, and anygrade below 60 is an F.This class needs to have some member variables. The first name, last name, the Z-number, thegrades, the total grade and final letter grade are all considered to be private member variablesof this class.The class should also have the following public member functions/procedural attributes that canbring the objects (students of the class) to life and give them some…

IN C++ Design a class called Date. The class should store a date in three integers: month, day, and year. There should be member functions to print the date in the following forms:12/25/2014December 25, 201425 December 2014 Demonstrate the class by writing a complete program implementing it. Input Validation: Do not accept values for the day greater than 31 or less than 1. Do not accept values for the month greater than 12 or less than 1.

C++ Write a class named Time It must have three private integer members named hours, mins and secs It must have a public constructor that sets the default time, hours, mins and secs to zero It must have two public member functions that are return type void. They must be settime with three integer arguments – this will allow the main function to reset the hours, mins and secs. show data with no arguments – this will allow the main function to display the time to the console. Use the main program as shown below to test your output against the output shown below:int main() {   Time a, b, c (8,20,10);  // declare 3 objects     b.settime(1,8,3);  // assign values to b's data members   a.showdata();      // display object a's values   b.showdata();      // display object b's values   c.showdata();      // display object c's values               return 0; }

Write a C++ program that does the following: Create a class called Student This class has the following private attributes: • Name • Age • GPA This class has the following methods: • Default constructor • Non-default constructor that will initialize all the above attributes • Set/Get method for each of the above attributes • DisplayStudent that will print the information for the student all three values on the same line with proper spacing • Destructor method that will print a message that the object has been deleted Your main function should do the following o Ask the user how many students to create • Create an array of objects of type Student (studentArr) o Call a function called acceptStudentinfo.This function will accept the array along with any needed parameters to allow the user to enter the values for the different students o Call a function called displayStudentlnfo. This function will accept the array along with any needed parameters to display the content of all students •…

1 // Rectangle.cpp 2 using namespace std; 3 class Rectangle ummary i this lab, you create a programmer-defined class and then use it in a C++ public: // Declare public methods here dpib;e| private: // Create length and width here double length; double width; rogram. The program should create two Rectangle objects and find their rea and perimeter. 8 istructions 10 11 1. Ensure the class file named Rectangle.cpp is open in your editor. 12 }; 13 2. In the Rectangle class, create two private attributes named length 14 void Rectangle::setLength(double len) 15 { and width . Both length and width should be data type double. 16 3. Write public set methods to set the values for length and width. 17 } 18 4. Write public get methods to retrieve the values for length and 19 void Rectangle::setWidth(double wid) 20 { width. 5. Write a public calculateArea() method and a public // write setWidth here 21 22 } calculatePerimeter() method to calculate and return the area of 23 the rectangle and the…
