Computer Science: Selection Statement (if-else) inside While Loop

This set of vocabulary flashcards covers the fundamental concepts of using selection statements (if-else) within while loops as presented in the computer science lecture.

While Loop

A programming structure that repeats instructions while a condition is true.

If Statement

A programming structure that checks a condition and runs code if that condition is true.

Syntax of a While Loop

$while$ condition: statement/s

Syntax of an If-Else Statement

$if$ condition: statement/s $else$ : statement/s

Indentation

A spacing format in Python that decides which statements belong inside the while, if, and else blocks.

Loop Variable Update

A required step where the counter or input must be changed (e.g., $count = count + 1$) so the loop eventually stops.

Increment

The process of adding a value to a counter, such as $count = count + 1$, to change the loop condition.

Selection

The process of decision making in code, such as choosing between "VIP Customer" and "Regular Customer" based on a condition.

Condition

A logical expression, such as $count <= 5$ or $count == 3$, that determines the flow of the program.

Else Action

The instruction that is executed when the initial "if" condition is false.

Infinite Loop

What happens in a program if the counter update is missing, causing the loop to potentially run forever.
