9.5 (complex Class) Create a class called complex for performing arithmetic with complex numbers. Write a program to test your class. Complex numbers have the form where i is V-I Use double variables to represent the private data of the class. Provide a constructor that enables an object of this class to be initialized when it's declared. The constructor should contain default values in case no initializers are provided. Provide public member functions that perform the following tasks: a. Adding two complex numbers: The real parts are added together and the imaginary parts are added together b. Subtracting two complex numbers: The real part of the right operand is subtracted from the real part of the left operand, and the imaginary part of the right operand is subtracted from the imaginary part of the left operand c. Printing Complex numbers in the form (a, b), where a is the real part and b is the imaginary part. 9.7 (Enhancing Class rime) Modify the Time class of Figs.9.4 D-9.5to include a tick member function that increments the time stored in a Time object by one second. Write a program that tests the tick member function in a loop that prints the time in standard format during each iteration of the loop to illustrate that the tick member function works correctly. Be sure to test the following cases: a. Incrementing into the next minute b. Incrementing into the next hour C. Incrementing into the next day (i.e., 11:59:59 PM to 12:00:00 AM) 9.8 (Enhancing Class Date) Modify the Date class of Figs. 9.13 -9.14 to perform error checking on the initializer values for data members month, day and year. Also, provide a member function nextDay to increment the day by one. Write a program that tests function nextDay in a loop that prints the date during each iteration to illustrate that nextDay works correctly. Be sure to test the following cases: a. Incrementing into the next month. b. Incrementing into the next year 9.9 (Combining Class rime and Class Date) Combine the modified rime class of Exercise 9.7 and the modified Date class of Exercise 9.8 into one class called DateAndTime . (in Chapter 11 , we'll discuss inheritance, which will enable us to accomplish this task quickly without modifying the existing class definitions.) Modify the tick function to call the nextDay function if the time increments into the next day. Modify functions printstandard and printUniversal to output the date and time. Write a program to test the new clasS DateAndTime. Specifically test incrementing the time into the next day

Answer 1

Answering the first part of your question :

The class ComplexNumber containing Add, Subtract and print functions.

#include <iostream>
using namespace std;

class ComplexNumber
{
private:
int realPart;
int imagPart;

public:
ComplexNumber(int r = 0, int i = 0): realPart(r), imagPart(i) {};

void setComplex(void)
{
cout << "Enter the realPart and imaginary parts : ";
cin >> this->realPart;
cin >> this->imagPart;
}  
ComplexNumber add(const ComplexNumber& c)
{
ComplexNumber comp;
comp.realPart = this->realPart + c.realPart;
comp.imagPart = this->imagPart + c.imagPart;
return comp;
}
ComplexNumber subtract(const ComplexNumber& c)
{
ComplexNumber comp;
comp.realPart = this->realPart - c.realPart;
comp.imagPart = this->imagPart - c.imagPart;
return comp;
}
void printComplex(void)
{
cout << "(" << this->realPart << ", " << this->imagPart << ")"<<endl;
}
};
