Programming Concepts

Conditions and Loops

Use conditions and loops with explicit predicates, finite progress, controlled exits, and visible final state.

UNTIMED COACHING

Practice before the pressure

Use feedback to correct the model, not merely memorize an option position.

GUIDED PRACTICE

Practice the lesson questions

Answer normal lesson questions without a timer. Every answer includes an explanation, and incorrect answers can be tried again before continuing.

CONCEPT MODELS

See the lesson as a system

Use these visual guides to connect the key ideas before answering the questions.

Map the program in Conditions and LoopsPlace boolean condition, conditional branches, for iteration, and while progress in distinct execution roles.
Map the program in Conditions and LoopsAn execution map connects input, decision, execution, and output roles to four concepts from conditions and loops.
Input modelBoolean condition

Execution stepFor iteration
Output evidenceWhile progress
Test Loop exits safelyConnect loop exits with a starting command, expected result, and explicit safety boundary.
Test Loop exits safelyA safe programming check connects loop exits with its command, result, and boundary.
Concept focusLoop exits
Starting commandRecord the exit reason and processed count
Expected resultOutcome for loop exits
Safety boundaryAn early exit can leave partial work unexplained
