💡 Quick Study Guide: Understanding Flowcharts
- 🗺️ A Flowchart is a diagram that shows the steps of a process or a program using different shapes and arrows.
- ➡️ Arrows (Flowlines): These show the direction of the flow, telling you which step comes next.
- 🔵 Oval (Start/End): This shape is used to show where a flowchart begins and where it finishes.
- 📦 Rectangle (Process): This shape represents a step or an action that needs to be done. For example, "Add 2 + 3".
- 💬 Parallelogram (Input/Output): This shape is used when you need to put information into the computer (input) or when the computer gives you information (output). For example, "Enter your name" or "Display result".
- ❓ Diamond (Decision): This shape asks a question that can be answered with "Yes" or "No". It helps the flowchart decide which path to take next.
- 🤖 Flowcharts help us plan computer programs and understand how things work step-by-step.
