Loop / loop body - correct answer A ________ is a program construct that repeatedly executes
the loop's statements (known as the loop body) while the loop's expression is true; when false,
execution proceeds past the loop.
while loop - correct answer A _______ that continues to repeat while a condition is true.
do-while loop - correct answer a ________ that first executes the loop body's statements, then
checks the loop condition. Compared to a while loop, a do-while loop is useful when the loop
should iterate at least once.
difference between while loop and do-while loop - correct answer While loop checks the
condition first and then executes the statement(s), whereas do while loop will execute the
statement(s) at least once, then the condition is checked.
for loop - correct answer a _______ consisting of a loop variable initialization, a loop
expression, and a loop variable update that typically describes iterating for a specific number of
times.
nested loop (inner/outer loop) - correct answer a ________ that appears in the body of
another loop
A program should continue accepting input numbers, adding each to a sum, until a 0 is input.
