I need to Write a class to store complex numbers and provide operations for the four basic arithmetic operations along with input and output operations. (You must have a class that has attributes of a real and an imaginary part. You would have 2 instances of this class for 2 complex numbers.) Use the time type project in your text to see help you with two class objects interacting.
Write a program to read two complex numbers and a symbol for one of these operations and to perform the indicated operations.  
Allow your program to continue until the user decides to Quit.

I need to write this for a case study, but i dón't really understand complex numbers.

Thanks in advance


Here are the formulas. Any help would be greatly appreciated, guidance is what i'm looking for.

A complex number has the form a + bi, where a and b are real numbers and
i² = -1.  The four basic arithmetic operations for complex numbers are defined as follows:

      addition:            (a + bi)+(c + di) = (a + c)+(b + d)i

      subtraction:            (a + bi)-(c + di) = (a - c)+(b - d)i

      multiplication:            (a + bi)*(c + di) = (ac – bd)+(ad + bc)i

      division:            a + bi = (ac + bd) + (bc – ad)  i
                        c + di   (c² + d²)    (c² + d²)

                        provided   both c and d do not equal zero

This sounds like an assignment for a course.  We cannot give you this type of answer, but we can help you if you get stuck.  Why don't you post what you have tried and then ask specific questions.

To do the above you don't really need to understand complex numbers.  Just look at the formulas that were provided and think about how you would implement that in code.

Yes, it is an assignment. I can write this easily in VB.net, i just cant figure it out forthe C# implementation.

Can i show what i have in vb ?

Sure.  But also you need to show what you have so far in C# and what is not working.  We can't do an assignement for you, but can help guide you if you have specific questions.  For example, "Why does ____ not compile" or stuff like that.
