🌟 Flowcharts: Your Roadmap for Computer Ideas

Introduction

A flowchart shows steps like a map for solving problems.
It helps computers and people understand tasks clearly.

1. What Is a Flowchart?

A flowchart is a picture of actions and decisions.
Each picture piece is called a Symbol.
Symbols connect with arrows that show the order.
You can read a flowchart from top to bottom.

Fun Fact: The first computer flowchart was drawn in the 1940s by IBM engineers.

2. Common Symbols and Their Meanings

• Oval: Marks the start or the end of a process.
• Rectangle: Shows an action, like “add numbers.”
• Diamond: Represents a yes‑or‑no decision point.
• Parallelogram: Indicates input or output, such as “type name.”

When you see a diamond, ask a question.
The answer decides which arrow to follow next.

3. How to Draw Your Own Flowchart

1. Write the problem you want to solve.
2. List each step in the order you think of them.
3. Choose the right symbol for every step.
4. Draw arrows that connect the symbols correctly.
5. Test the chart by pretending to follow it.

Deeper Explanation:
Programming languages turn flowcharts into code.
Each symbol becomes a line of instructions that computers execute.

4. Real‑world Uses of Flowcharts

• Designing video‑game levels.
• Planning school projects or chores.
• Explaining how a website loads pages.
• Teaching robots to sort objects.

Mini Experiment & Quiz

Experiment: Make a Sandwich Flowchart

1. Gather bread, cheese, and ham.
2. On paper, draw an oval labeled “Start.”
3. Add a rectangle: “Take two slices of bread.”
4. Add a rectangle: “Place cheese on one slice.”
5. Add a rectangle: “Add ham on top of cheese.”
6. Add a diamond: “Do you want lettuce?”
   • Yes → rectangle: “Add lettuce.”
   • No → skip to next step.
7. Draw a rectangle: “Put second slice on top.”
8. End with an oval: “Enjoy your sandwich!”

Follow the arrows to make a real sandwich.
