OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
T F
The private members of a class may be directly accessed from function "main"
Step by step
Solved in 2 steps
- C++ simple friend function. Create a C++ class called cube that calculates the volume of a cube. Use appropriate accessors (getters) and mutators (setters), constructors, etc. Your program must also include a friend function that will sum the volume of two cube class instances. Output the individual volumes of each of the two cube classes and then the total volume from the friend function.True or False: 1. Data items in a class may be public. 2. Class members are public by default. 3. Friend functions have access only to public members of the class.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
- c++ oop Write a program that creates a class called Number. Your class will have two data membersnamely num (float) and result (int). To find the factorial of the entered number you will need todesign three functions as follows: Function to determine if a number is a whole number or not Function to determine if the number is positive or not Function to find the actual factorial Function to display the number and its factorial (Must be constant function) All these required function should be class’s functionRemember that to find the factorial, the number must of positive and a whole number. So if anyof these conditions are not met then you cannot determine the factorial.Create a class of Person having private data members. Make all constructors along with setter getter. Also make a print function that can print all the information of that person.Class Person{Private:char* name;int age;Job job;};Class Job{Private:int id;char * role;int salary;};error_outlineHomework solutions you need when you need them.

Provide a constructorthat enables an object of this class to be initialized when it isinstantiated. The constructor should contain default values in case noinitializes are provided.Provide Public member functions for each of the followingoperations: set the time, print the time, increment the time by onesecond, compare two times for equality, increment the time by onehour, determine if one time is “less than” (comes before) anothertime, and final print the time in format 12 hours.Include any additional operations that you think would be useful foryour class.Design, implement, and test your class.
- 1. Class Time ( Operator Overloading) PLEASE READ THE MAIN FUNCTION. DO NOT CHANGE THE MAIN FUNCTION. COMPLETE THE PROGRAM TO GET THE CORRECT OUTPUT. 【Description】 Write a program to define a class Time, which contains three member variables: hour, minute and second Please realize the following functions with operator overloading: input and output time with >> and << use += and -= increase and decrease the time ,e.g.Time& operator+=(const Time&);Time& operator-=(const Time&); 【Input】 There are two line, each line is the time of a clock Input format:hour minute second。 【Output】 There are two lines. The first line is the output of time1 += time2 ; The second line is the output of time1 -= time2 ; Output format:hour:minute:second; Please read the 【Input example】 21 10 35 10 15 25 【Output example】 07:26:00 21:10:34 THE INCOMPLETE CODE. NOTE: Do not change the main function #include <iostream>using namespace std; class Time{…T/F A method defined in a class can access the class' instance data without needing to pass them as parameters or declare them as local variables.(phyton) create a vehicle claas with max_speed and mileage. define a function that changes the max speed with the setMax_speed(new speed) function. Create an object of this class change the max_speed value of this object to 200 with the help of the function you defined
