C++.

Design a class called DaysWorked. The class's purpose is to store a value mHours that could be evaluated in terms of days of work. For example: - 8 hours are actually 1 day of work - 12 hours are 1.5 days of work - 18 hours are 2.25 days of work The class should have a default constructor, and an overloaded constructor that accepts a number of hours. The class should also have the following overloaded operators: - + The addition operator: When two DaysWorked objects are added together, this operator should return a new object that has mHours equal to the sum of the two objects mHours. - - The subtraction operator: When two DaysWorked objects are subtracted, this operator should return a new object that has mHours equal to the difference between the two objects mHours. - ++ Prefix and postfix increment operators: These operators should increment the number of hours in the object. When incremented, the number of days of work should be recomputed. - -- Prefix and postfix decrement operators: These operators should decrease the number of hours in the object. When decremented, the number of days of work should be recomputed. - << cout stream insertion operator: This operator should display to the screen all objects data in a clear fashion. - >> cin stream extraction operator: This operator should prompt the user to enter all the object's data in a clear fashion. - == equality comparison operator: This operator should return true if both objects have equal mHours member variables - [] subscript operator: This operator should return days if subscript is 0, hours if subscript is 1, and error out a message otherwise.

The below driver program should display the following output:

int main() {

DaysWorked lObjOne; DaysWorked lObjTwo; cin >> lObjOne; cin >> lObjTwo; DaysWorked lObjThree = lObjOne + lObjTwo; cout << endl << "lObjThree = lObjOne + lObjTwo: " << endl; cout << lObjThree; DaysWorked lObjFour(10); lObjOne = lObjThree - lObjFour; cout << endl << "lObjOne = lObjThree - lObjFour: " << endl; cout << lObjOne; cout << "lObjOne[0]: " << lObjOne[0] << endl; cout << "lObjOne[1]: " << lObjOne[1] << endl; cout << "lObjFour = lObjOne++: " << endl; lObjFour = lObjOne++; cout << lObjOne; cout << lObjFour; cout << "lObjFour = ++lObjOne: " << endl; lObjFour = ++lObjOne; cout << lObjOne; cout << lObjFour; cout << "lObjFour = lObjOne--: " << endl; lObjFour = lObjOne--; cout << lObjOne; cout << lObjFour; cout << "lObjFour = --lObjOne: " << endl; lObjFour = --lObjOne; cout << lObjOne; cout << lObjFour; if (lObjFour == lObjOne) cout << "lObjFour is equal to lObjOne" << endl; else cout << "lObjFour is NOT equal to lObjOne" << endl; system("PAUSE"); return 0; }
