Question

Design a class Complex for handling Complex numbers and include the following:

_ real: a double

_ imaginary: a double

The class has the following member functions.

a. A constructor initializing the number with default parameters.

b. Getters and Setters of the class data members as given below

_ void setReal(double r)

_ double getReal()const

_ void setImaginary(double i)

_ double getImaginary() const

d. Overload unary ! operator which returns true if the real and the imaginary parts are zero, otherwise return false.

bool opeator!()const

rite main function to test all the implemented functionality

class Complex {
   double real;
   double imaginary;
public:
   Complex();
   Complex(double,double);

   void setReal(double r);
   double getReal()const;

   void setImaginary(double i);
   double getImaginary() const;

   bool operator!()const;

   virtual ~Complex();
};

Answer 1

I have implemente the class and the code is below.

=====================================================================

 #include<iostream> using namespace std; // class to implement the complex number // It will contain the real value and imaginary value. class Complex { // variables to store the values double real; double imaginary; public: // Default Constructor to initialis the complex number with 0. Complex(){ this->real = 0; this->imaginary = 0; } //Constructor to initialise the complex number with the given value. Complex(double real,double imaginary){ this->real = real; this->imaginary = imaginary; } // Setter function which sets the real value void setReal(double r){ this->real = r; } // getter function which gets the real value. double getReal()const{ return this->real; } // setter function to set the Imaginary value. void setImaginary(double i){ this->imaginary = i; } // Getter function which gets the Imaginary value. double getImaginary() const{ return this->imaginary; } // ! operator which return true if real and imaginary part is zero otherwise false bool operator!()const{ if(this->real==0 && this->imaginary == 0){ return true; } else{ return false; } } // it sets the real and imginary part to zero after the execution of the program. virtual ~Complex(){ this->real = 0; this->imaginary = 0; } }; // main function to test the complex class. int main(){ Complex c1,c2; // declaring the object of class complex. double r,i; cout<<"Enter the Real value : "; cin>>r; cout<<"Enter the Imaginary value : "; cin>>i; c1.setReal(r); // setting the real value c1.setImaginary(i); // setting the imaginary value. cout<<"The complex number you enterd is "; // getting the value of real and imaginary part. cout<<c1.getReal()<<" + "<<c1.getImaginary()<<"i"<<endl; cout<<"If c1 has value in real and imaginary part it will print 0 otherwise 1: "; cout<<!c1<<endl; cout<<"The deafult complex number is "; cout<<c2.getReal()<<" + "<<c2.getImaginary()<<"i"<<endl; cout<<"If c2 has value in real and imaginary part it will print 0 otherwise 1: "; cout<<!c2<<endl; return 0; }

And the screenshot of my code editor is below.

And output of the above code is:

I hope this will help.
