Question

C++ PLEASE

This will be a multi-part assignment. Later homework will expand upon what is developed in this assignment.

1. Create a class called MyComplex to represent complex numbers. Each part (Real and Imaginary parts) should be stored as a double. Data members should be private and you need to supply appropaiate accessor and mutator methods.

2. Supply a default constructor (both parts zero), a constructor that allows the real part to be set and a third constructor that allows both parts to be set.

3. Supply an insertion operator that will allow the value of a complex number to be printed. The output should look like: 2+3i, 1-4i, -2+0i, 0+5i for example.

4. Supply a complete program that exercises your class. (be sure you also exercise the accessor and mutator functions). You must supply a listing of your program and sample output.

Answer 1

//Programm is as below-

#include<iostream>

using namespace std;

class MyComplex{
  
   private:

//private data members
       double realPart;
       double imaginaryPart;
      
   public:
//defaukt constructor
       MyComplex(){
           realPart=0;
           imaginaryPart=0;
       }
      

//constructor which is setting only real part and hence imaginary part is zero
       MyComplex(double real){
           this->realPart=real;
           this->imaginaryPart= 0;
       }
      

//constructor which is setting both the real and imaginary part
       MyComplex(double real, double imaginary){
           this->realPart =real;
           this->imaginaryPart = imaginary;
          
       }
//Accesor   

double getReal(){
           return realPart;
       }
      
       double getImaginary(){
           return imaginaryPart;
       }
      

//Mutator
       void setRealPart(double real){
           this->realPart = real;
       }
      
       void setImaginaryPart(double imaginary){
           this->imaginaryPart = imaginary;
       }

//display function which will display the complext number
       void display(){
           if(imaginaryPart >= 0){
               cout << realPart << "+" <<imaginaryPart<< "i"<<"\n";
           }else{
                   cout << realPart <<imaginaryPart<< "i"<<"\n";
           }
          
       }
};

int main(){
//creating object of MyComplex class and displaying
   MyComplex complexNumber(2,3);
   complexNumber.display();
  
   MyComplex complexNumber2(1,-4);
   complexNumber2.display();
  
   MyComplex complexNumber3(-2);
   complexNumber3.display();
  
   MyComplex complexNumber4(0,5);
   complexNumber4.display();
}
