Design a Job class with three data fields-Job number, time in hours to complete the Job, and per-hour rate charged for the Job.


Include overloaded extraction and insertion operators that get and display a Job's values.


Include overloaded + and - operators that return integers that indicate the total time for two Jobs, and indicate the difference in time between two Jobs, respectively.


Write a main()function demonstrating that all the functions work correctly.


Create a Person class that includes fields for last name, first name, and zip code. Include a default constructor that initializes last name, first name, and zip code to “X” if no arguments are supplied. Also include a display function. Write a main()function that instantiates and displays two Person objects: one that uses the default values, and one for which you supply your own values. Save the file as Person.cpp. Y


Write a program that prompts the user to enter five integers that you store in an array. Write a function called quadruple() that takes a single-integer parameter and multiplies it by 4, returning the result to the calling program. Call the function once for each of the five integers, then display the quadrupled results from within the main() function.
Create a class named Car. The Car class contains a static integer field named count. Create a constructor that adds 1 to the count and displays the count each time a Car is created. Create a destructor that subtracts 1 from the count and displays the count each time a Car goes out of scope. Write a main() function that declares an array of five Car objects. Output consists of five constructor messages and five destructor messages, each displaying the current count.
Create two classes DM and DB to store the value of distances.DM stores distances in meters and centimetres and DB in feet and inches. Write a program that can read values for the class object and add one object of DM with another object of DB. Use a friend function to carry out the addition operation. The object that stores the results may be a DM or DB object depending on the units in which the results are required. Type display should be in feet-inches or meter-centimetre depending on the object of display.

You are given two integers, a and b. Print the smallest value among a%b and b%a.




Write down 3 positives and 3 negative test cases for all of the 45 testing techniques

Write a program having Classes Rectangle with data members’ length and width, Square with data member side ,EquilatralTrainglewith data member side . All these classes are derived from class Shape. Write an independent function which will exhibit polymorphism and show the area of the object passed to the function. All data members of class are private; you can write suitable functions needed for you.

The file named called EMPLOYEE.txt contains employee details such as employee number, name, designation and salary of employee. Write a program to create a file to store the details of employee (Use of structure and fwrite () & fread () functions).
