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:

Explain the concept of function definitions outside a class using the following scenario:A University needs to calculate the fees of students. Explain the required class and function definition outside the class clearly writing a program.python language Write a function that overwrite the greater than method for a class. The class has a field variable called score. The lower the score, the better. INPUT: Nothing?

- Describe how you can use an interface as an alternative to a class to specify the type for a parameter.T/F 2. Formal parameters are those that appear in the method call and actual parameters are those that appear in the method header.2019 AP® COMPUTER SCIENCE A FREE-RESPONSE QUESTIONS 2. This question involves the implementation of a fitness tracking system that is represented by the StepTracker class. A StepTracker object is created with a parameter that defines the minimum number of steps that must be taken for a day to be considered active. The StepTracker class provides a constructor and the following methods. addDailySteps, which accumulates information about steps, in readings taken once per day activeDays, which returns the number of active days averageSteps, which returns the average number of steps per day, calculated by dividing the total number of steps taken by the number of days tracked The following table contains a sample code execution sequence and the corresponding results. Statements and Expressions Value Returned Comment (blank if no value) StepTracker tr StepTracker(10000); Days with at least 10,000 steps are considered active. Assume that the parameter is positive. new tr.activeDays () ; No…
- Java A class always has a constructor that does not take any parameters even if there are other constructors in the class that take parameters. Choose one of the options:TrueFalseIn C++, Create a class called Date that includes three data members: amonth(type int), a day(type int), and a year(type int). The Date class willhave a constructor with three parameters to initialize the three data members.You may assume the values provided for the year and day are correct, but makesure that the month value is in the range 1-12; if it isn't, set the month to1. Provide set and get functions for each data member. Provide a memberfunction displayDate that displays the date in format MM/DD/YYYY.Write a test program that prompts the user to input the month, the day,and the year and uses your Date class to output the formatted date.Language: C++ Next a thirst level (as double value) should be added to the properties of a critter. Add a new constructor that takes five parameters for setting all properties of a critter. Make also sure that the existing constructors will still work. For the existing constructors, the thirst level should be set to the same level as the hunger level. Your existing testcritter.cpp must still be able to run in its unchanged form. So the already existing constructors need to support the change. Name the files Critter.h, Critter.cpp and testcritter.cpp. Finally, you should adapt the print method for printing on the screen also the value of the thirst level as a double. The client program testcritter.cpp may contain one additional line, where the constructor taking five parameters is being called. You can assume that the setting values are always valid.
- Write a Rectangle class that has the following fields: Length (L): a double - Width (W): a double The class should have the following functions: Constructor: accepts the length (L) and the width (W) of a rectangle as arguments. Constructor: does not take any parameters and initializes the length(L) and width(W) to zero. - A function called getArea which returns the area of the rectangle. A function called getPerimeter which returns the perimeter of the rectangle. {note: The area of a rectangle =L*W, and its perimeter = 2*(L+W) } Then, write a program to ask the user to enter the length and width of a rectangle, and then use the above class to calculate and print the area and perimeter of the rectangle.Instructions: In the code editor, you are provided with a treasureChestMagic() function which has the following description: Return type - void Name - treasureChestMagic Parameters - an address of an integer Description - updates the value of a certain integer randomly You do not have to worry about how the treasureChestMagic() function works. All you have to do is ask the user for an integer and then call the treasureChestMagic() function, passing the address of that integer you just asked. Finally, print the updated value of the integer inputted by the user. Please create a main code for my function that works with this. This is my code: #include<stdio.h>#include<math.h> void treasureChestMagic(int*); int main(void) { // TODO: Write your code here return 0;} void treasureChestMagic(int *n) { int temp = *n; int temp2 = temp; *n = *n + 5 - 5 * 5 / 5; temp2 = (int) pow(2, 3); if(temp % 3 == 0) { *n = temp * 10; } else if(temp %…#this is a python program #topic: OOP Design a class Joker with parameterized constructor so that the following line of code prints the result shown in the output box.
