Next we provide a file complex.cpp where the code and algorithms of
different functions (except inlined functions) declared within the
class are written. The files complex.h and complex.cpp are normally
placed in a directory with other classes and libraries we have
defined.
Finally, we discuss here an example of a main program which uses this particular class. An example of a program which uses our complex class is given below. In particular we would like our class to perform tasks like declaring complex variables, writing out the real and imaginary part and performing algebraic operations such as adding or multiplying two complex numbers.
