The Design Process

Which step of the development process is described below?

Andrew interviews his client to determine what the expectations are for the software that he has been hired to create.

• Design

• Prototyping

• Testing

• Investigating and reflecting

Which of the following best describes one of the benefits of using an iterative and incremental process of program development?

• It allows programmers to implement algorithmic solutions to otherwise unsolvable problems.

• It eliminates the need for programmers to test completed programs.

• It enables programmers to create programs that use the lowest-level abstractions available.

• It helps programmers identify errors as components are added to a working program.

Which of the following is a true statement about program documentation?

• Program documentation should not be changed after it is first written.

• Program documentation is only needed for programs in development; it is not needed after a program is completed.

• Program documentation is useful when programmers collaborate but not when a programmer works individually on a project.

• Program documentation is useful during initial program development and also when modifications are made to existing programs.

Which of the following are examples of tasks which are to be done during the investigating and reflecting phase of development?

• communicate with potential users to determine specifications

• test code segments and correct errors

• outline a possible solution to the problem

• clearly define the problem that is to be solved

Which of the following statements about code comments is true?

• comments in code change the way the program is executed

• it is not necessary to use comments in your code unless you are working with other programmers

• code comments are beneficial when developing and maintaining a program

• comments should only be added to code after the program is complete

During which phase of the software development cycle would you be most likely to engage in brainstorming?

• Investigating and Reflecting

• Designing

• Prototyping

• Testing

Which of these best describes the purpose of a program’s specifications?

• directions on how the program should be used

• promises about what a program is able to do

• data that are used by the program

• a list of errors which need to be corrected

The process of repeating the steps of designing, implementing, testing, and refining is described as

• incremental

• prototyping

• collaborative

• iterative
