String array
A variable should hold the names of all past U.S. presidents. Which
data type should the variable be?
Constant integer secondsPerMinute
A program uses the number of seconds in a minute in various
calculations. How should the item that holds the number of seconds in
a minute be declared?
Constant integer minAge

x / 2 + 0.5 /2 + .25
Given float x = 3.0. Which expression evaluates to 2.0?
( x >= 18) and ( x <= 24)
Which expression evaluates to true only when the user is within 3
years of 21 years, given a variable x containing a user's age?
Float
Which data type is used for items that are measured in length
, Integer
Which data type should be used to keep track of how many planes are
in a hangar?
Hours and minutes
A function should convert hours and minutes to seconds, such as
converting 1 hour and 10 minutes to 4,200 seconds. What should be the
input to the function?
x
A function returns a number x cubed. For example, if x is 3, the
function returns 3 3 3, or 27. What should be the input to the
function?
Diff
A function calculates the weight difference (Diff) given two sample
weights (S1 and S2). What should be the output from the function?
10
function P(integer x) returns integer y y = 2 * x What does P(5)
evaluate to?
HeyHeyHey
Function F() Put "Hey" to output What entire output appears after
three successive calls to F()?
a valid identifier
What is a valid user-defined function name?
z only
A function MyFct has an input x and an output z.What does MyFct
return?
Output of a function
What is the return value of a function?
While loop
A program should continue accepting input numbers, adding each to a
sum, until a 0 is input.Which control structure should be used?
Do-while loop
Joe is building an online game. He wants to provide a riddle and have
the player guess the answer. The game needs to prompt the user to
enter the answer, check to see if it the input provided does not
match the correct answer, and continue prompting the user until the
answer entered matches the correct answer.Which control structure
supports Joe's needs?
3 2 1
What is put to output by the following pseudocode? x = 3do Put x to
output Put " " to output x = x - 1while x > 0
'Hello' will print indefinitely.
A programmer has developed the following code: count = 0while count
is less than 5: print 'Hello' What is the result of implementing this
code?
