WAP to create two different files name like roll and name of at least 5 students and print all on screen.

Information like name and roll number and read that file and print the content on screen. Write a program using which you will able to create file student info in which you need to provide necessary.

Create a class named Complex which contains:

• data field named real of type double
• data field named imag of type double
• no-arg constructor that initializes real & imag to 0
• parametrized constructor with specified values for real & imag
• overloaded stream extraction operator << that will display a complex number in the form a + bi
• overloaded stream insertion operator >> that will ask the user for real and imag part of the complex number
• overloaded binary + operator and a binary – operator
• overloaded binary * operator and / operator
• function mag() that will return the magnitude of the complex number.
• function conjuage() that returns the conjugate of a complex number

Sample:

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

1: Addition

2: Subtraction

3: Multiplication

4: Division

5: Magnitude

6: conjugate

9: Quit

Enter your selection: 1

C1 + C2 = 7 - 2i
