Lab Exercises 1. Write a program named lab4.cpp that contains a class named Student to store student information. Information that will be relevant to store is first name, last name, id number, GPA, and major. 1. Define a member function named set(), which allows you to set all member variables. This function has an empty parameter list, and its return type is void. So, within the function you'll prompt for information. Note: For entering major, if you need a space, use an underscore. (i.e. Computer Science would be Computer Science) 2. Define a member function named print() that prints a summary of the Student object. You can choose how this data is formatted to the screen (you can use the sample run format). 3. Create a driver file to test your class. You should instantiate at least 3 objects of Student type. Note, this should NOT be an array of Student. Use 3 different Student object declarations. We will cover arrays of objects later.

A Mutator function within a class must have access to the private data item but Accessor functions should not. True False Question 32 4 pts The private and public areas of a class can appear in any order. In other words the public declarations or private declarations can come first...it does not matter. True False

Task 2: use c++ to Create an employee class, basing it on Task 1. The member data should comprise an int for storing the employee number and a float for storing the employee’s compensation. Member functions should allow the user to enter this data and display it. Write a main() that allows the user to enter data for three employees and display it.

C++ Write a function named “createPurchaseOrder” that accepts the quantity (integer), the cost per item (double), and the description (string). It will return a newly created PurchaseOrder object holding that information if they are valid: quantity and cost per item cannot be negative and the description cannot be empty or blank(s). When it is invalid, it will return NULL to indicate that it cannot create such PurchaseOrder object.

Which of the following statements is true about a class' member function definition?     a. A function definition provides a class name, return type, arguments, and the functions’ statements.   b. A function definition provides the function’s name, return type, and arguments.   c. A programmer first defines a function and then declares the member functions.   d. A modulus operator is used preceding the function’s name in a function definition.

Each function inside the class A(n)_ is a virtual function. Provide your thoughts by filling in the blanks.

Rewrite the calculator program using a class called calculator. Your program will keep asking the user if they want to perform more calculations or quit and will have a function displayMenu to display the different functions e.g .(1 - addition, 2- subtraction, 3- multiplication, 4- division)   Your program must have appropriate constructors and member functions to initialize, access, and manipulate the data members as well as : A member function to perform the addition and return the result A member function to perform the subtraction and return the result A member function to perform the multiplication and return the result A member function to perform the division and return the result

C++ Write a function named “createPurchaseOrder” that accepts the quantity(integer), the cost per item (double), and the description (string). It will return anewly created PurchaseOrder object holding that information if they are valid:quantity and cost per item cannot be negative and the description cannot be empty or blank(s). When it is invalid, it will return NULL to indicate that it cannot create such PurchaseOrder object. PurchaseOrder createPurchaseOrder(int quantity, double costPerItem, string description) {     if(quantity < 0 || costPerItem < 0.0 || description == "")         return NULL;     else     {         PurchaseOrder p = new PurchaseOrder(quantity,costPerItem,description);         return p;     } } what's the issue with this function and how to rewrite it
