Problem Solving and Programming Design (Part 2)

What is Programming Life Cycle (PCL)?

• The Programming Life Cycle (PCL) is a structured process that guides the development of software through various stages.
• A framework for designing user interfaces.
• A method for debugging code errors.
• A set of programming languages used in software development.

How many phases are PCL?

• 9

• 8

• 7

• 6

What are the phases in PCL?

• Specify the problem

• Analyze the problem

• Implement the algorithm

• Design Algorithm to solve the problem

• Test and verify the completed program

Type of Maintenance

• Corrective

• Sensitive

• Adaptive

• Preventive

• Perfective

Meaning of Specify the Problem

• To specify Input & Output

• Processing requirement

• System Constraints

• review program specification

Meaning of Analyze the problem

• develop a detailed logic plan

• To review program specification

• define the problem to solve and write program

• error handling methods

What is Design Algorithm to solving the problem?

• develop tool by creating the user interface

• test algorithm

• develop a detailed logic plan

• using psedocode, flowchart, object structure diagram

What is Implement the algorithm?

• develop tool by creating the user interface

• test algorithm

• develop a detailed logic plan

• translate design into application using programming language

What is test and verify the completed program?

• develop tool by creating the user interface

• test algorithm

• Fine correct error until free error

• provide education and support

What is Maintain Update?

• identify user requested

• correct any unanticipated

• provide education and support

• correct error
