# Fall 2016 Exam 1 Review

Exam #1 will be given on Wednesday, September 28th during regular class hours. It will begin at 2pm and you will have 75 minutes to complete the exam. The exam will cover the introductory materials from the first day of class, as well as Chapters 1-8 of Sprankle. No notes or reference materials will be allowed for use during the exam. You will be allowed a calculator to check your math, but you probably won't need it.

The format of the exam will be as follows:

• Multiple Choice. There will be a series of multiple choice questions to test your basic knowledge of terms and problem-solving concepts.
• Short Answer. You will be asked to define, identify, or explain various problem-solving concepts based on the material that has been discussed in lecture.
• Problems. In this section, you will be asked to solve problems. For example, you may be given flowchart segments and asked to describe or list what the output would be. Alternatively, you may be asked to design a flowchart to perform a particular action. These problems will be similar to the lab activities and homework you have completed for this class.

For examples of each of the types of questions you'll see on the exam, here is a mini exam (key) I have created for you.

Introduction and Chapter 1: General Problem-Solving Concepts

• Be able to define a computer, as well as the elements of the IPOS cycle (with examples)
• Know and be able to sort the six steps of the problem-solving process

• What are some factors that can help you decide which decision logic structure to use?

Chapter 7: Problem-Solving with Loops

• What is the difference between incrementing and accumulating?
• Know and understand the terms "initialize" and "priming read" in relation to Dr. Rita's While Loop Checklist!
• Understand the major similarities and differences between While loops and Repeat/Until loops in relation to (1) test location, (2) when the loop is broken, (3) priming reads, and (4) minimum number of iterations
• Know how to construct basic While, Repeat/Until, and Automatic-Counter loops
• Be able to follow the logic of a nested loop to determine what the output would be based on given input
