PRG211 Algorithms and Logic for Computer Programming

Week 1 Discussion

Algorithms

Consider a potential business problem that would require a computer program solution. Discuss how an algorithm might be used to solve a problem that a business may encounter.

Supporting Activity: Additional Discussion Questions

1.  Why is a flowchart useful in developing and documenting software?

2.  Why is the interactive Visual Logic flowchart program more useful than a manually drawn flowchart?

3.  Is a flowchart more valuable in documenting the logic of a program than just the coded instructions in the programming language? Explain your answer.

4.  What are the similarities and differences between procedures and objects?

5.  What is an example of software that would be best implemented in procedural programming?

6.  What is an example of software that would be best implemented in object- oriented programming?

Week 2 Discussion

Flowcharts

Explain what is meant by a modular approach to programming. Why is this approach important?

Supporting Activity: Flowcharts

What challenges did you encounter when creating your first Visual Logic flowchart?

How can the Visual Logic program be used to determine the effect a single grade (such as a B or C) will have on your grade point average (GPA)?

Week 5 Discussion

Direct and Random Access

In which situations would you choose to use a direct access or random access file instead of a sequential access file? Give a specific example and explain your reasoning.

Supporting Activity: Data Hiding

Explain the term data hiding, which is used in object-oriented programming. Is data hiding a valuable security consideration? Why or why not?
