Question

In C++ what would be the correct way to write this specific portion or a program? I already have the Test class definition written.

Add the following methods to the Test class definition:

1. Additional constructor with 2 parameters
   • Signature: Test(double realParam, double imaginaryParam)
   • Allows a Test object to be created with the specified real variable (variable name = real) and imaginary variable (variable name = imaginary) parts.
2. copy constructor
   • Signature: Test(const Test &copyTest)
   • Copies the data members from copyTest to this object.

Answer 1

The below is the code for the specified two methods:

        //constructor with two parameters
       Test(double realParam, double imagainaryParam)
       {
           //create a Test object with specified real and imaginary variables
           real = realParam;
           imaginary = imagainaryParam;
       }
      
       //copy constructor
       Test(const Test &copyTest)
       {
           real = copyTest.real;
           imaginary = copyTest.imaginary;
       }

Placing the methods in a class definition would be as below:

class Test
{
   private:
       double real;
       double imaginary;
      
   public:
       //constructor with two parameters
       Test(double realParam, double imagainaryParam)
       {
           //create a Test object with specified real and imaginary variables
           real = realParam;
           imaginary = imagainaryParam;
       }
      
       //copy constructor
       Test(const Test &copyTest)
       {
           real = copyTest.real;
           imaginary = copyTest.imaginary;
       }
};
