Question

Define a data type for representing complex numbers. (A complex number consists of 'real' and 'imaginary' parts. The real and imaginary parts can represent the x and y coordinates of a point on a plane.) How can a complex data type be created? (pick correct choice in Illustration 2 )

Answer 1

Answer:

A complex data type can be created by the use of class or structures.

#include <iostream>

using namespace std;

class complex{//creating a class complex to store a complex value.

public://defining all the values public.

int real;

int img;

complex(int real,int img)//parameterized constructor.

{

    this->real=real;

    this->img=img;

}

};

int main() {

   complex n1(1,2);//n1 is a complex number with real part 1 and imaginary part 2.

   cout<<n1.real<<" i"<<n1.img<<endl;

return 0;

}

Output

1 i2

Explanation:

I have created a class complex to store complex number with two integer parts real and imaginary.You can also declare them float if you wan to store decimal values and after that i have created a parameterized constructor with real and imaginary values.So we can assign the values at the time of declaration of the object of class complex.
