A flowchart is a diagrammatic representation of a problem-solving process, i.e., an algorithm.
It's like a map that helps people understand how something works by using different shapes connected by arrows. Each shape has a specific meaning, and the arrows show the order or direction of the steps.
Here are the basic flowchart symbols:
- Oval (Start/End): This shows where the process begins and ends. Every flowchart has at least one start and one end.
- Rectangle (Process): Represents an action or task that needs to be done. It’s the main step in the process.
- Diamond (Decision): Shows a point where a decision is made. This shape usually asks a "yes" or "no" question, and the flow splits based on the answer.
- Parallelogram (Input/Output): Used to show when data is taken in (input) or results are given out (output).
- Arrow (Flow Line): Arrows connect the shapes and show the order of the steps, telling you what comes next.
- Circle (Connector): These are circle-shaped symbols that are used to join the parts of a flowchart
In a flowchart, you start from the top or the "Start" shape, follow the arrows through the different steps or decisions, and finally reach the "End" shape. It's an easy way to break down a complicated process so that everyone can follow it step by step.
