Se condary memory, such as a disk , CD, or flash drive, does not lose its contents when power is removed from the computer. 24. A syntax error is the misuse of a key word, operator, punctuation, or other part of the programming language. A logical error is a m istake that tells the computer to carry out a task incorrectly or to carry out tasks in the wrong order. It causes the program to produce the wrong results. 25. C 26. B 27.

Some of the questions that should be asked are: What standard ceiling height should be used, or is this figure to be input? How many square feet should be subtracted out for windows and doors, or do you also want this information input since it could vary by room? Are the ceilings also to be painted , or just the walls? How many squ are feet will 1 gallon of paint cover? How many coats of paint will you use , or should this information be input?

On line 7 t here should be a semicolon after int a, b, c . In addition, the comment symbol is incorrect. It should be //. On lines 8 -10 each assignm ent statement should end with a semicolon. On line 11 cout begins with a capital letter. In addition, the stream insertion operator s should read << instead of >> and the variable that is ouput should be c instead of capital C. 30. Whatever problem a pai r of students decides to work with they must determine such things as which values will be input vs. which will be set internally in the program, how much precision is required on calculations, what output will be produced by the program, and how it should be displayed. Students must also determine how to handle situations that are not clear cut. In the paint problem many of these considerations are listed in the teacher answer key (Chapter 1, Question 34). In the recipe program students must determine such things as how to handle quantities, like one egg, that cannot be halved. In the driving program, knowing distance and speed are not enough. Agreement should be reached on how to handle delays due to traffic lights and traffic congestion. Should this be a n input value, computed as a percent of overall driving time, or handled some other way?
