Assume the definition of class foodType as given in Exercise 6.
Answer the following questions? (1, 2, 3, 5, 6)
Write the definition of the member function set so that private members are set according to the parameters. The values of the int and double instance variables must be nonnegative.
Write the definition of the member function print that prints the values of the data members.
Write the definitions of the member functions getName, getcalories, getFat, getSugar, getCarbohydrate, getPotassium to return the values of the instance variable.

- How we can access protected data members of a class without the use of public or private functions? Explain with codearrow_forwardNutritional information (classes/constructors) PYTHON ONLY Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name (a string) to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's10.034.02.01.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is:…arrow_forwardCreate an Employee class that includes three private data members— firstName (type string), lastName (type string), and monthlySalary (type int ).It also includes several public member functions.1. A constructor initializes the three data members. 2. A setFirstName function accepts a string parameter and does not return any data. It sets the firstName.3. A getFirstName function does not accept any parameter and returns a string. It returns the firstName.4. A setLastName function accepts a string parameter and does not return any data. It sets the lastName.5. A getLastName function does not accept any parameter and returns a string. It returns the lastName.6. A setMonthlySalary function accepts an integer parameter and does not return any data. It sets the monthlySalary. If the monthly salary is less than or equal zero, set it to 1000 and it displays the employee’s first name, last name and the inputted salary with a statement “**==The salary is set to $1000.”7. A getMonthlySalary…arrow_forward
- Write a class ‘Box’ which has three members height, width and depth; To set values and use these members, write mutator and accessor functions for these members. (Hint: there would be 3 Accessor and 3 Mutator functions).arrow_forwardPlease read the main function and define a class CStudent. (object array, static member, string) Please do not change the main function and complete the program given. 【Description】 Please read the main function and define a class CStudent. In the main funciton, two arrays of the ojbect of CStudent are define. Please analyze the call of constructor and destructor in the process of creating and releasing objects. 1. CStudent has two private member variables:stirng name, int age. 2. CStudent has a static member count. It will be incremented by 1 when the object is created and decremented by 1 when the object is destroyed. 3. The constructor function should output "*** is contructing". The destructor function should output “*** is destructing”. "***" indicates the name of the current CStudent object. 【Input】 No input 【Output sample】 There are 0 students. noname is contructing noname is contructing noname is contructing noname is contructing noname is contructing name:noname…arrow_forwardWrite a class Travel having two private data members (distanceCovered , Time) The class has three constructors which are • having no parameter – for setting values to zero or null. • having two parameters for assigning values to both data members. • Overload the above constructor and use this keyword to set the values of data members. • Provide getters/setters for data members. • A function which calculates and display speed of traveling. • Write a function show() displays values. Write test Application that demonstrates the Run class by calling all the three constructors and method, creating a Create Travel objects, and then display the traveling with speed.

Define the class studentType with the same components as the struct studentType, and add member functions to manipulate the data members. (Note that the data members of the class studentType must be private.) Write a program to illustrate how to use the class studentType. Struct studentType: struct studentType { string firstName; string lastName; char courseGrade; int testScore; int programmingScore; double GPA; }; An example of the program is shown below: Name: Sara Spilner Grade: A Test score: 89 Programming score: 92 GPA: 3.57 ***************arrow_forwardQUESTION 3 A constructor is like a function. It can return any type value needed. True Falsearrow_forward
- True or False: In order to derive class A from class B, class A must contain a public member function that may be called by the rest of the class. (It is not a half-finished project.) A) This is correct. B) The answer is False.arrow_forwardTrue or false? Only instance member functions can be defined as constant functions.arrow_forwardObject oriented programming C++ Use Classes Write a C++ program in which each flight is required to have a date of departure, a time of departure, a date of arrival and a time of arrival. Furthermore, each flight has a unique flight ID and the information whether the flight is direct or not.Create a C++ class to model a flight. (Note: Make separate classes for Date and Time and use composition).add two integer data members to the Flight class, one to store the total number of seats in the flight and the other to store the number of seats that have been reserved. Provide all standard functions in each of the Date, Time and Flight classes (Constructors, set/get methods and display methods etc.).Add a member function delayFlight(int) in the Flight class to delay the flight by the number of minutes pass as input to this function. (For simplicity, assume that delaying a flight will not change the Date). Add a member function reserveSeat(int) which reserves the number of seats passed as…arrow_forward
