Introduction to Code Quiz: Test Your Understanding (Grade 7)

📚 Quick Study Guide

• 💻 What is Code? Code is a set of instructions that tells a computer what to do.
• ✏️ Variables: Variables are used to store information that can be used later. Think of them as labeled containers.
• ➕ Operators: Operators perform actions like addition (+), subtraction (-), multiplication (*), and division (/).
• 🔀 Conditional Statements: Conditional statements (like 'if', 'else if', 'else') allow your code to make decisions based on certain conditions.
• 🔁 Loops: Loops allow you to repeat a block of code multiple times. Common types include 'for' and 'while' loops.
• 🚀 Functions: Functions are reusable blocks of code that perform a specific task.
