Self-Test Exercise 18 asked you to overload the operator >> and the operator << for a class Percent. Complete and test this exercise. Implement the default constructor and the constructor with one int parameter. Overload the + and − operators to add and subtract percents. Also, overload the * operator to allow multiplication of a percent by an integer. Write a

- 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_forward1- Implement the class “cylinder” with member variables radius and height, whichare private of type double. Define the global constant PI=3.1415 and use it incalculating the volume of the cylinder (PI*radius*radius*height).Implement in the class cylinder the following functions:a- A default constructor with default values of one.b- One constructor with two arguments. This constructor should check that thevariable is positive and does not exceed 20, otherwise the variable will beassigned its default value of one.c- A reader for each variable.d- A writer for each variable.e- A reader and a writer for diameter.f- A member function “volume” which calculates the volume of a cylinder.g- A member function “print” which prints the radius, diameter, and height of acylinder.h- A member function display_name() which displays “cylinder”.2- Write a program which declares an array of n cylinders (use n=5). Initialize thearray values by writing a loop which asks the user to input the radius and…arrow_forwardSUBJECT: OOPPROGRAMMING LANGUAGE: C++ ALSO ADD SCREENSHOTS OF OUTPUT. Write a class Distance to measure distance in meters and kilometers. The class should have appropriate constructors for initializing members to 0 as well as user provided values. The class should have display function to display the data members on screen. Write another class Time to measure time in hours and minutes. The class should have appropriate constructors for initializing members to 0 as well as user provided values. The class should have display function to display the data members on screen. Write another class which has appropriate functions for taking objects of the Distance class and Time class to store time and distance in a file. Make the data members and functions in your program const where applicablearrow_forward
- Using Cpp/C++ Create an Account class that a bank might use to represent customers’ bankaccounts. Include a data member of type int to represent the account balance. [Note: In subsequentchapters, we’ll use numbers that contain decimal points (e.g., 2.75)—called floating-point values—to represent dollar amounts.] Provide a constructor that receives an initial balance and uses it to initializethe data member. The constructor should validate the initial balance to ensure that it’s greaterthan or equal to 0. If not, set the balance to 0 and display an error message indicating that the initialbalance was invalid. Provide three member functions. Member function credit should add anamount to the current balance. Member function debit should withdraw money from the Accountand ensure that the debit amount does not exceed the Account’s balance. If it does, the balanceshould be left unchanged and the function should print a message indicating "Debit amount exceededaccount balance." Member…arrow_forwardproblem statement: Write a java classStringCheckto do the below given checks on accepted string or strings. Each function should be coded in separate methods of the class. Give appropriate instance variables to implement the method. The user should be able to enter the string through the main function in Main class. Use a constructor to initialize the String entered by the user. Use the Main class to test all the methods in StringCheckclass. The programs should have the below given checklist: 1)Define classStringCheck with required instance variables 2)The StringCheck class should have six methods to do the below functions: *Check if the user entered string is a simple sentence? (Starts with capital letter, Ends with period, space between words). *Check if the user entered string is a question? (Check if the string starts with ac apital letter ends with a question mark, space between words) *Check if the user entered string have numbers in it? *Check if string is a valid email *Check…arrow_forwardWrite a student class that will keep track of the grades of students and generates a final mark. •You should store three quiz marks, each out of a total of 20 marks, one midterm score out of a total of 50 marks, one final project out of 100 and an overall score with a letter grade associated with it. Further, create the respected accessor and mutator methods necessary. •The function calculateOverallScore() should calculate the weight as follows; quizzes are 15% total, midterm is 35% total and final is worth 50% for a total of 100% when summed up. •The function finalLetterGrade() should return the letter based off the following: 100-90 A, 90-80 B, 70-80 C, 60-70 D, 0 – 60 F •When complete create a student object, set the marks for quizzes/midterm/final and print the letter and final grade to the console.arrow_forward
- JAVA write grading program for a class with the following grading policies. thers a total of 2 quizzes, each graded on the basis of 10 points. theeres is 1 midterm exam and one final exam, each graded on the basis of 100 points. final exam counts for 50% of the grade, the midterm counts for 25%, and the 2 quizzes together count for a total of 25%. (Do not forget to normalize the quiz scores.) letter grade will be given based on the following criterion: 90 – 100 A 80 – 89 B 70 – 79 C 60 – 69 D 0 – 59 E program will read student’s scores from a txf file, save them in an arrayor arrays), process the arrays), print the student’s record, which consists of the name, 2 quiz and 2 exam scores as well along with students avg numscore for the course and final letter rade. please noteAll the scores are integers and a student name consists of no more than 10 characters. justify output filearrow_forwardWrite ONLY Header (No body{}) of function for each question. You can use any valid variable name for the input parameters. Assume that the following is a tester program of GameObject class, and answer the questions. int main (){ GameObject player (3, 100, 'M'); GameObject enemy (4, 100, 'F'); player.print(); } Guess the GameObject class and functions from the code above, and write the header of constructor. You can use any valid variable name for the input parametersarrow_forwardInstructionsDefine an enumeration type triangleType that has the values scalene, isosceles, equilateral, and noTriangle.Write a function triangleShape that takes as parameters three numbers, each of which represents the length of a side of the triangle. The function should return the shape of the triangle. (Note: In a triangle, the sum of the lengths of any two sides is greater than the length of the third side.)Write a program that prompts the user to input the length of the sides of a triangle and outputs the shape of the triangle.arrow_forward
- Create a class called Employee that includes four pieces of information as data members — a first name (type string), a middle name (type string) , a last name (type string)and a monthly salary (type int). Your class should have a constructor that initializes the four data members. Provide a set and a get function for each data member. If the monthly salary is not positive, set it to 0. Write a test program that demonstrates class Employee’s capabilities. Create two Employee objects and display each object’s yearly salary.arrow_forwardQuestion P .Write the implementation (.cpp file) of the Acc2 class of the previous exercise. The full specification of the class is: An data member named sum of type integer. A constructor that accepts no parameters. THe constructor initializes the data member sum to 0. A function named getSum that accepts no parameters and returns an integer. getSum returns the value of sum . Full explain this question and text typing work only We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this linearrow_forwardWrite code to create a class named as ‘Employee’ with attributes i.e. ID, Name, Designation, Qualification, Salary, Taken-Leaves, Allowed-Leaves and the functions applyLeave(). This function will take number of leaves as an input and check Allowed-Leaves to see whether the employee can take leaves or not. If he can take, deduct these leaves from Allowed-Leaves and add in Taken-Leaves. Otherwise show message ‘you cannot take leave’. Create another class ‘Intern’ and inherit ‘Employee’ as super class.arrow_forward
