Chapter 12, Problem 1D

Explanation of Solution

 Object oriented design:

• A set of process that is involved in developing a set of classes for problem solving is called as object oriented design.
• It is considered as most powerful complement to the top-down design for developing a reliable, cost-effective software system.
• The goal of top-down design is developing set of black-boxes and its associated interfaces.
• A top-down design seeks for the function whereas the Object Oriented Design seeks for an Object.

Process of Object oriented design OOD:

There are many different ways to process OOD and they are as

• Look for object candidates.
  • While considering a problem definition, the main goal is to define a set of objects that aids in solving the problem.
  • The objects that are chosen are often described through nouns.
  • The nouns present in the each problem statement are considered and underlined one by one based on the below mentioned factors.
• Identify instance variables.
  • Based on the value possessed by the instance variable the instance variables are identified.
  • Most of the instance variables are considered to have primitive value whereas some of them seem to have complex types...
