Answer: Declare variables distMiles and speedMphdistMiles = endLocation
- startLocationspeedMph = distMiles / timeHoursPut speedMph to output
,◍ What is put to output by the following pseudocode? x = 3do Put x to output
Put " " to output x = x - 1while x > 0.
Answer: 3 2 1
◍ What does the following algorithm determine?if x == y z = 1 else z = 0.
Answer: Whether x and y are the same
◍ A function calculates the weight difference (Diff) given two sample weights
(S1 and S2). What should be the output from the function?.
Answer: Diff
◍ What does an output of 1 indicate for the following algorithm running on a
five-element list of integers? i = 0 x = 0 while i < 5 if list[i] < 0 x = 1 i = i +
1 Put x to output.
Answer: At least one integer is negative
◍ What does the following algorithm accomplish? x = Get next input if x ==
-1 Put "Goodbye" to output.
Answer: Outputs Goodbye when user types -1
◍ Which phase of an agile approach would define a hypothesis to find a
problem in a program?.
Answer: Testing
◍ What is an advantage of interpreted programs?.
Answer: They can be modified at run time.

Answer: Tags surround text to describe desired formatting.
◍ Naming conventions.
Answer: A set of style guidelines defined by a company, team, teacher, etc.,
for naming variables.
◍ Arguments.
Answer: Any function input values, appear within ( ), and are separated by
commas if more than one.
◍ Given float x = 3.0. Which expression evaluates to 2.0?.
, Answer: x / 2 + 0.5 /2 + .25
◍ Interpreted Language.
Answer: A language that is run one statement at a time by another program
called an interpreter.
◍ Array.
Answer: An ordered list of items of a given data type.
◍ Statically typed.
Answer: Each variable's type must be declared and cannot change while the
program runs.

last (4).A Declare variable minB Put min to outputC min = xD If y < min,
set min = y.
Answer: ACDB
◍ Dynamically typed.
Answer: A variable's type may change while a program executes, based on
what is assigned to the variable.
◍ Variables.
Answer: To refer to data, like x.
◍ A programmer wants a compiler to report an error if an integer variable is
assigned with a string. Which kind of language should the programmer use?.
Answer: Statically typed
◍ Which characteristic specifically describes interpreted languages?.
Answer: They can run on any machine having the right interpreter.
◍ Characters.
Answer: Any letter (a-z, A-Z), digit (0-9), or symbol (~, !, @, etc.).
