Word scramble
Unscramble the letters and write each key term on the line.
1
FI A DNA B
In a flowchart, AND is two diamonds in a row: only Yes then Yes reaches the action, and a No from either diamond goes to the same next step.
2
FI A RO B NEHT
In a flowchart, OR is two diamonds whose Yes arrows both reach the same action. The second diamond sits on the first's No path. The action is skipped only if both are No.
3
SEETDN FI SV NDA
IF A AND B gives the same result as IF A THEN IF B when one action needs both tests. Use nesting when each test needs its own different ELSE outcome.
4
OPCUNMOD OOPL XTEI
A loop test using AND or OR is drawn as a back arrow to the first question, with one combined diamond or two diamonds. Both exit reasons must lead out of the loop.
5
HEWIL + FI + NAN/DO/TRO
A complete design where a loop repeats, IF decisions use AND, OR or NOT, and the flowchart and the pseudocode do the same job, so both versions agree.

1FI A DNA B → IF A AND B — In a flowchart, AND is two diamonds in a row: only Yes then Yes reaches the action, and a No from either diamond goes to the same next step.
2FI A RO B NEHT → IF A OR B THEN — In a flowchart, OR is two diamonds whose Yes arrows both reach the same action. The second diamond sits on the first's No path. The action is skipped only if both are No.
3SEETDN FI SV NDA → nested IF vs AND — IF A AND B gives the same result as IF A THEN IF B when one action needs both tests. Use nesting when each test needs its own different ELSE outcome.
4OPCUNMOD OOPL XTEI → compound loop exit — A loop test using AND or OR is drawn as a back arrow to the first question, with one combined diamond or two diamonds. Both exit reasons must lead out of the loop.
5HEWIL + FI + NAN/DO/TRO → WHILE + IF + AND/OR/NOT — A complete design where a loop repeats, IF decisions use AND, OR or NOT, and the flowchart and the pseudocode do the same job, so both versions agree.
