1 Name: May 1, 2013 NOCTI Study Guide Coding Programs! Yesterday s Study Questions. Correct Answer are included. 1. A typical non-functional user requirement is/are A. What the user interface looks like b. The user s constraints and purposes C. the resources needed to maintain the system d. The actions the system performs automatically Answer C because the resources needed to maintain the system is an example of a typical nonfunctional user requirement. 2. The following programming flowchart symbol is a/an. a. Processing b. Input/output c. Decision d. connector Answer C because the symbol in the item is a decision symbol. A decision symbol is a junction where a decision must be made. 3.One of the main goals in analyzing user requirements is to a. Troubleshoot the problem b. Shutdown and maintain the system c. Keep the customer happy d. Elicit requirements from a user s point of view Answer D because one of the main goals in analyzing user requirements is to elicit requirements from a user s point of view. 4. Which of the following flowchart symbols indicates a question or branch in the process flow? a. Connector b. Decision c.process d. Extract Answer B because flowchart symbol indicates a question or branch in the process flow. 5. If a record has the following field lengths, what is the record length? Name=35, Zipcode=5, District =7 a. 42 b. 47 c. 54 d. 56 Answer B because with field lengths of 35, 5 and 7, the record length would be 47. To arrive at the record length, add the field lengths together. 6. The implementation phase consists of coding, testing, and a. Designing b. Building prototype programs c. Establishing requirements d. Integration Answer D because the implementation phase consists of coding, testing, and integration of a program. 7. Reviewing specifications is the step in writing a computer program. a. First b. Second c. Third d. Fourth Answer A because the first step in writing a computer program is reviewing specificiations. 8. Coding is the step in a writing a computer program. a. First b. Second c. Third d. Fourth Answer C because coding is the third step in writing a computer program. 9. The following programming flowchart symbol is a/an symbol. a. Processing b. Input/output c. Decision d. Connector Answer B because the symbol in the item is an input/output symbol. An input/output symbol represents data that is available for input or resulting from processing. 10. How to use various logic diagrams to describe flow of data and processing (e.g. meaning of logic diagram symbols)?
