C Program to perform complex numbers operations using structure. Complex numbers are numbers which contains two parts, real part and imaginary part. Complex numbers are written as a+ib, a is the real part and b is the imaginary part. We used the structure in C to define the real part and imaginary part of the complex number.

## 2 comments on “C Program to perform complex numbers operations using structure.”

I am here to discuss about a number which can be put in the form a + bi termed as complex number, where a and b are real numbers and i is called the imaginary unit,in given expression "a" is the real part and b is the imaginary part of the complex number. The complex number can be identified with the point (a, b).
