Chapter 2, Problem 23RQE

Program Plan Intro

Pseudocode:

• Pseudocode is the informal, text based description of the operations in the program or an algorithm.
• Pseudocode is platform independent which means that the pseudocode can run in any operating system such as Windows, IOS or Linux. This feature makes it easy for the user to run and understand the code.
• It includes the structural details of normal programming language but excludes the details required to make it understandable by machine rather it focuses on making it understandable by humans.
• It is used in books which deals with algorithm design and also becomes the basic structure while developing a computer program.
• While writing a pseudocode it is necessary that the vocabulary used in the pseudocode should explain the problem statement in details rather than explaining the implementation details.

Forms of pseudocode:

• High level pseudocode:
  • High level pseudocode is the list of steps that should be performed in the program.
• Detailed pseudocode:
  • Detailed pseudocode is the expanded version of high level pseudocode.
  • It mentions all the details like the mathematical operations which are not mentioned in high level pseudocode.
