ever causes the condition to
become false, a(n) ________ may
occur.
6) True/False: A while loop is
True
somewhat limited because the
counter can only be
incremented or decremented
by one each time through the
loop.
7) A(n) ________ is a variable that
loop control variable
controls the number of times a
loop iterates.
8) A(n) ________ is a variable that
is regularly incremented or
decremented each time a loop
iterates.

post test, pretest
________ loop, whereas the while
loop is a(n) ________ loop.
12) True/False: You can nest a
False
for loop inside another for
loop, but cannot nest a while
loop inside another while loop
or a do-while loop inside
another do-while loop.

of a do-while loop are
executed
14) True/False: Before
