Add appropriate constructors and member functions to initialize, access, and manipulate the data members and this class should implement abstract method of class PersonType. c) Design the class billType with data members to store a patient’s ID and a patient’s hospital charges, such as pharmacy charges for medicine, doctor’s fee, and room charges. Add appropriate constructors and member functions to initialize and access and manipulate the data members. d) Design the class patientType, inherited…Hello, I am having trouble with this homework question for my c++ course. Implement a Rational Number class with the following specifications. Data members a) numerator and denominator Functions a) Constructors: 1) default constructor 2) single parameter constructor to create numerator/1 3) dual parameter constructor to create numerator/denominator 4) Use constructor delegation across all constructors. b) Accessors and Mutators for both data members. c) Static recursive GCD function using Euclid's algorithm. d) Static LCM function for two numbers. e) Reduce function simplify a rational number. This function modifies its calling object. f) Your program should work with the supplied driver program. Notes LCM (Least Common Multiple) This function returns the smallest multiple of a and b. Step 1: Multiply a and b to find a common multiple. Step 2: Divide the common multiple by the GCD of a and b. Step 3: Return the result of Step 2. Reduce: This function reduces a fraction to…Following the instructions presented in the Lecture 4.5 and 4.6, complete the class Bag we discussed in the lectures.

- a. Extend the definition of the class complexType so that it performs the subtraction and division operations. Overload the operators subtraction and division for this class as member functions. If (a, b) and (c, d) are complex numbers, (a, b) - (c, d) = (a - c, b - d), If (c, d) is nonzero, (a, b)/(c, d) = ((ac + bd)/(c ^2+ d ^2 ), (-ad + bc)/(c ^2 + d^ 2 )) b. Write the definitions of the functions to overload the operators – and / as defined in part a. c. Write a test program that tests the various operations on the class complexType.

- Overload all relational operators (<, >, <=, >=, ==, and !=) for Box class. The boxes must be compared based on their volumes. The output should be the same as from the last assignment but now you must use overloaded operator functions instead of the normal member functions to accomplish your task. A sample output is given below: There are 4 Boxes in this program. Box 1 dimensions: length = 5'-3", width = 2'-7.5", height = 3'-8" and volume = 50.53 Box 2 dimensions: length = 4'-6", width = 9'-3", height = 2'-4" and volume = 97.12 Box 3 dimensions: length = 4'-6", width = 9'-3", height = 2'-4" and volume = 97.12 Box 4 dimensions: length = 3'-3", width = 9'-3", height = 2'-4" and volume = 70.14 Box 2 and Box 3 are equal. The largest box has dimensions: length = 4'-6", width = 9'-3", height = 2'-4" and volume = 97.12 The smallest box has dimensions: length = 5'-3", width = 2'-7.5", height = 3'-8" and volume = 50.53 by using c++Overload all relational operators (<, >, <=, >=, ==, and !=) for Box class.
