The following menu driven C++ program uses operator overloading to to perform Addition,Subtraction,Multiplication and Division of two complex numbers.Here Operators +,-,* and / are overloaded to perform the required operations with the desired objects.

eg:a*b in the terms of overloading means is to perform the '*' Operation associated with object a on object b.

The Complete Source Code is given below.If you have any Queries Just Comment on the Post.

Thankz buddy..! helped a lot

why should we use objects in member functions when it can directly access its data members?

nice !!

hey can someone please write this complex number program for me? i would greatly appreciate it. write a C++ programme to carry out mathematical operations on complex numbers without using the predefined complex function available with your compiler. The operations to be carried out on both complex and polar form numbers must include but not be limited to:

Addition and subtraction of two or more vectors

Multiplication and division

Converting from complex form to polar form

Converting from polar form to complex form

Conjugate and modulus of the complex number

Your solution should include at least two classes, one Complex and the other Polar.

The mathematical operations should be able to operate on both types of numbers at the same time, e.g.:

Complex A, x;

Polar B, y;

x = A + B;

y = A * B;

i get this erroe

thanks for helping me complete my holiday homework

Please anyone help me to understanding the logic of "/" operator.

It does not working :-(

Write a program using function to find the product of complex numbers. Use structure to store the complex numbers. The function takes the two complex numbers as argument and returns the complex numbers.

Great and Useful Article.
