True/False
Indicate whether the
statement is true or false.

|
|
1.
|
You can only use variable memory locations to control the data type of numbers
used in calculations.
|
|
|
2.
|
Both constant and variable memory locations make your code more self-documenting
and easier to understand.
|
|
|
3.
|
You can use variables to store the values of processing items, which do not
appear in a user interface.
|
|
|
4.
|
One advantage of variables and named constants is that their use requires fewer
lines of code.
|
|
|
5.
|
As the amount of code increases, so does the likelihood for errors.
|
|
|
6.
|
Program bugs typically are caused by either syntax errors or logic
errors.
|
|
|
7.
|
Logic errors are the easiest to find.
|
|
|
8.
|
The Code Editor detects most syntax errors as you enter the instructions.
|
|
|
9.
|
The Code Editor makes logic errors easy to find and correct.
|
|
|
10.
|
Some logic errors occur as a result of calculation statements that are correct
syntactically, but incorrect mathematically.
|
|
|
11.
|
When debugging, while the execution of a procedure’s code is paused, you
can view the contents of controls and variables that appear in the highlighted statement, as well as
in the statements above it in the procedure.
|
|
|
12.
|
Stepping through code one line at a time is the only way to search for logic
errors.
|
|
|
13.
|
Many times the next instruction processed depends on the result of a decision
that must be made.
|
|
|
14.
|
A programmer determines whether a problem’s solution requires a selection
structure by studying the problem specification.
|
|
|
15.
|
Items in square brackets are required in the syntax of an algorithm.
|
|
|
16.
|
Arithmetic operators are evaluated after any comparison operators in an
expression.
|
|
|
17.
|
The oval in a flowchart is called the selection/repetition symbol.
|
|
|
18.
|
The two flowlines leading out of a diamond should be marked so that anyone
reading the flowchart can distinguish the true path from the false path.
|
|
|
19.
|
You can select a check box by double-clicking it.
|
|
|
20.
|
When a check box is selected, clicking it again deselects it.
|
|
|
21.
|
Unlike the variables declared at the beginning of a procedure, variables
declared within a statement block in a selection structure remain in memory until the procedure
ends.
|
|
|
22.
|
Unlike variables declared at the beginning of a procedure, variables declared
within a statement block have block scope rather than procedure scope.
|
|
|
23.
|
Although there is nothing wrong with declaring all variables at the beginning of
a procedure, many programmers would prefer to create a variable only if it is necessary to do
so.
|
|
|
24.
|
More unintentional errors occur in applications when the variables are declared
using the minimum scope needed.
|
Multiple Choice
Identify the
choice that best completes the statement or answers the question.
|
|
|
25.
