Conditional logic (if-then decisions) in Intro to Computing - Flowchart & Logic Diagram

Process Overview

Conditional logic helps a computer decide what to do next by checking if something is true or false. It’s like making a choice based on a question.

Do action

This flowchart shows a simple if-then decision: the computer checks a condition, then does one action if true, or another if false, then ends.

Step-by-Step Trace - 5 Steps

Step 1: Start the decision process

Step 2: Check if the condition is true

Step 3: If condition is true, do the first action

Step 4: If condition is false, do the other action
