Answer to Question #276654 in C++ for pica

Question

In this assignment, you will create a class named Complex. The class contains:

• A data field named real of type double
• A data field named imag of type double
• A no-arg constructor that initializes real & imag to 0
• A parametrized constructor with specified values for real & imag
• An overloaded stream extraction operator << that will display a complex number in the form a + bi
• An overloaded stream insertion operator >> that will prompt the user for real and imag part of the complex number
• An overloaded binary / operator

Sample run:

Enter the first complex number .  . .

Enter real part:  3

Enter imag part: 4

Enter the second complex number .  . .

Enter real part:  4

Enter imag part: -6

You entered the numbers ...

C1 = 3 + 4i

C2 = 4 – 6i

The division of two complex numbers:

C1 / C2 = -12/52 + 34/52 i

Would you like to input more numbers? (y/n) n

Thank you for using complex numbers app!
