,Section 1.2 Program Development Cycle
1. An algorithm is defined as:
(A) a mathematical formula that solves a problem.
(B) a tempo for classical music played in a coda.
(C) a logical sequence of steps that solve a problem.

4. In most cases, a well-written program need not be tested. (T/F)
F
5. The analysis and design steps of program planning are largely independent of the particular
computer language the programmer is using. (T/F)
T
6. When starting a new program, it is best to start writing code as soon as possible to avoid
wasting time thinking about it. (T/F)
F
7. Often a problem is too difficult to understand until one writes the program. (T/F)
F
8. Although the documentation step is usually listed last in the problem-solving process, it
should actually begin when the problem is first defined and continue through the problem-
solving process. (T/F)
T
,9. Order the steps in the program development cycle starting with 1 for the first step and so on.
