Create a class Distance with feet and inches as a private dada members. Feet has int type and inches has float type. Create getdist & showdist functions which take values from user and then display these values respectively. Create another class Sign with sign as a private data member. Sign has a char data type. Class sign is inherited with distance class. Create getdist and showdist function to get values from user and then display all values. Create default & arrguments constructor also. Add a static data member named objCount, initialize it to 0 using scope resolution operator outside the class, add a function in the class to print the value of objCount.
(Enhanced Employee Class) Modify class Employee inFigs. 12.9–12.10 by adding a private utility function calledisValidSocialSecurityNumber . This member function shouldvalidate the format of a social security number (e.g., ###-##-#### , where # is a digit). If the format is valid, return true ;otherwise return false .
3.10 (Invoice Class) Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four data members —a part number (type string ), a part description (type string ), a quantity of the item being purchased (type int ) and a price amount exceeded per item (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. In addition, provide a member function named getInvoiceAmount that calculates the invoice amount (i.e., multiplies the quantity by the price per item), then returns the amount as an int value. If the quantity is not positive, it should be set to 0 . If the price per item is not positive, it should be set to 0 . Write a test program that demonstrates class Invoice ’s capabilities.
Account Class) Create an Account class that a bank might use to represent customers’ bank accounts. Include a data member of type intto represent the account balance. Provide a constructor that receives an initial balance and uses it to initialize the data member. Theconstructor should validate the initial balance to ensure that it’s greater than or equal to 0. If not, set the balance to 0 and display anerror message indicating that the initial balance was invalid. Provide three member functions. Member function credit should add anamount to the current balance. Member function debit should withdraw money from the Account and ensure that the debit amountdoes not exceed the Account’s balance. If it does, the balance should be left unchanged and the function should print a messageindicating "Debit amount exceeded account balance." Member function getBalance should return the current balance. Create a programthat creates two Account objects and tests the member functions…
Create a SavingsAccount class. Use a static data member annualInterestRate to store the annual interest rate for each of the savers. Each member of the class contains a private data member savingsBalance indicating the amount the saver currently has on deposit. Provide member function calculateMonthlyInterest that calculates the monthly interest by multiplying the savingsBalance by annualInterestRate divided by 12; this interest should be added to savingsBalance. Provide a static member function modifyInterestRate that sets the static annualInterestRate to a new value. Write a driver program to test class SavingsAccount. Instantiate two different objects of class SavingsAccount, saver1 and saver2, with balances of $2000.00 and $3000.00, respectively. Set the annualInterestRate to 3 percent. Then calculate the monthly interest and print the new balances for each of the savers. Then set the annualInterestRate to 4 percent, calculate the next month’s interest and print…
(Rational Class) Create a class called Rational for performing arithmetic with fractions.Write a program to test your class. Use integer variables to represent the private data of the class—the numerator and the denominator. Provide a constructor that enables an object of this class to beinitialized when it’s declared. The constructor should contain default values in case no initializersare provided and should store the fraction in reduced form. For example, the fractionwould be stored in the object as 1 in the numerator and 2 in the denominator. Provide publicmember functions that perform each of the following tasks:a) Adding two Rational numbers. The result should be stored in reduced form.b) Subtracting two Rational numbers. The result should be stored in reduced form.c) Multiplying two Rational numbers. The result should be stored in reduced form.d) Dividing two Rational numbers. The result should be stored in reduced form.e) Printing Rational numbers in the form a/b, where a is…
(Rational Numbers) Create a class called Rational for performing arithmetic with fractions. Write a program to test your class. Use integer variables to represent the private instance variables of the class—the numerator and the denominator. Provide a constructor that enables an object of this class to be initialized when it's declared. The constructor should store the fraction in reduced form. The fraction 2/4 is equivalent to 1/2 and would be stored in the object as 1 in the numerator and 2 in the denominator. Provide a no-argument constructor with default values in case no initializers are provided. Provide public methods that perform each of the following operations: a) Add two Rational numbers: The result of the addition should be stored in reduced form. Implement this as a static method. b) Subtract two Rational numbers: The result of the subtraction should be stored in reduced form. Implement this as a static method.…
(Protected vs. Private Base Classes) Some programmers prefer not to use protected accessbecause they believe it breaks the encapsulation of the base class. Discuss the relative merits of usingprotected access vs. using private access in base classes.
1.1 Class definition Define a class bankAccount to implement the basic properties of a bank account. An object of this class should store the following data: Account holder’s name (string) Account number (int) Account type (string, check/savings/business) Balance (double) Interest rate (double) – store interest rate as a decimal number. Add appropriate member functions to manipulate an object. Use a static member in the class to automatically assign account numbers. 1.2 Implement all appropriate member functions of a class. 1.3 write a program that illustrate how to use your class. Your program should have the following: Declare an array of 20 components of type bankAccount to process up to 20 customers. void menu() – helps the user to select if the customer is new or if they already exist. Furthermore, it prints the customer’s data or exits the program. Use a switch statement which uses the value from menu() as an expression to call the following user-defined functions: void…
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;};
Bank Account Class Part (1) Define a class with the following specification:(a) The class name is BankAccount and it has two private variables: fullName (String) and balance (double). (b) Write a constructor that initializes fullName and balance variables. If balance is negative, then set it to 0.0 and print the message “Invalid balance. Balance is set to 0.0”. (c) Provide a set and get methods to balance variable. In set method, if the supplied balance (parameter) is negative print an invalid message and do not change the balance.(d) Write a method deposit() that has one double input parameter called amount. The method adds amount to the current balance.(e) Write a method withdraw() that has one double input parameter called amount. The method subtracts amount from the current balance.(f) Write method printInfo() that displays the full name on a single line followed by the balance on the next line. Part (2) Write a Java application to test the class you defined in Part (1):(a) Ask…
