Flowcharts for visualizing logic in Intro to Computing - Flowchart & Logic Diagram

Process Overview

A flowchart is a simple drawing that shows the steps and decisions in a process. It helps us understand how a task flows from start to finish by using shapes and arrows.

Input number

↓

Print "Positive"

This flowchart shows how to check if a number is positive or not. It starts by getting a number, then decides if it is greater than zero. If yes, it prints 'Positive'; if no, it prints 'Zero or Negative'.

Step-by-Step Trace - 5 Steps

Step 1: Start the process

Step 2: Input a number, for example 5

Step 3: Check if number > 0

Step 4: Since True, print 'Positive'

Step 5: End the process

This diagram shows the flow of data: input goes to a decision, which leads to one of two outputs depending on the condition.
