function myNewFunction(integer x) z = x - 3returns integer yWhat is the parameter? -
✔✔✔integer x What happens if you define a function but do not call it? - ✔✔✔Nothing. The
code will simply remain in memory but will not execute. A function, anyKey, has an input x
and an output z. What does anyKey return? - ✔✔✔z function popcorn(integer k) returns
integer y y = k * 2 What does popcorn(12) evaluate to? - ✔✔✔24 function math(integer x)
returns integer y y = 3 * x + 1 What does math(5) evaluate to? - ✔✔✔16 Function hello() Put
"Hello my friend" to output What output appears after two successive calls to the
function? - ✔✔✔Hello my friendHello my friend Using the following function, which portion
is the function declaration? function myFunction(integer b) a = b - 3 returns integer a + b
myFunction(6) - ✔✔✔function myFunction(integer b) Using the following function, which
portion contains the function's argument? function myFunction(integer b) a = b - 3 returns
integer a + b myFunction(6) - ✔✔✔myFunction(6) Using the following function, which
portion calls the function? function myFunction(integer b) a = b - 3 returns integer a + b
myFunction(6) - ✔✔✔myFunction(6) Using the following function, which portion defines
the output? function myFunction(integer b) a = b - 3 returns integer a + b myFunction(6) -
✔✔✔returns integer a + b Your user needs to enter a number into the program that will be
used throughout its execution. Before the user enters a number, which loop type can
determine how many times the loop will run? - ✔✔✔for Which loop types are best suited to
continually check a test expression? - ✔✔✔while do while What type of loop is best suited
to perform operations over a range of values? - ✔✔✔for What type of loop is shown here? -
✔✔✔while What is the purpose of an "if" statement? - ✔✔✔To control what code executes
based on the result of a test expression. What is it called if a "while" statement's test
expression never changes to false? - ✔✔✔Infinite Loop How many times can you call a
function to run? - ✔✔✔as many times as you want. What is the primary difference between
a "while" loop and a "do while" loop? - ✔✔✔The "do while" is guarenteed to run at least
once before testing the condition. How many times will this loop iterate? for i = 0; i < 4; i = i
+ 1; // Loop statements - ✔✔✔four times Fill in the blank so that the loop will iterate 10
times. for i = 1; _________; i = i + 1; // Loop statements - ✔✔✔i <= 10 What is put to output
by the following pseudocode? x = 4 while x >= 0 Put x to output x = x - 2 - ✔✔✔420 What is
put to output by the following pseudocode? x = 6 while x > 0 Put x to output Put " " to output
x = x - 2 - ✔✔✔6 4 2 How many times does this loop run? a = 8 b = 4 while a % b == 0: Put a
to output b = b + 2 Loop Application Project - ✔✔✔1 Which control structure is best to look
at the individual grades of each student for Task 1? - ✔✔✔for loop Which control structure
