class to do some computation. We will see this design aspect when we discuss classes and
What is the use of creating 2 methods when we could do the same thing in one method?
There are a lot of powerful things which can be done when we do it this way. First, we
are delegating a task to be done to another method. This itself makes it possible to divide
the programming work among many people at the same time. The design of the software
product becomes easier when we divide the design into many parts.
