posttest

The ______ loop condition is evaluated after the instructions within the loop are processed

posttest

A loop whose condition is evaluated after the instructions in its loop body are processed

posttest loop

pretest

The ______ loop condition is evaluated before the instructions within the loop are processed

pretest

A loop whose condition is evaluated before the instructions in its loop body are processed

pretest loop

A false code that, although it resembles programming language instructions, it cannot be understood by a computer

pseudocode

The control structure that directs the computer to repeat one or more instructions until some condition is met, at which time the computer should stop repeating the instructions

repetition structure

To keep a posttest loop from processing at least once, use a ______ structure

selection

The control structure that directs the computer to make a decision and then take the appropriate action based on that decision

selection structure
