Repeat and Forever Loops in Scratch Quiz: Test Your Knowledge!

📚 Quick Study Guide

• 🔄 Repeat Loop: Executes a block of code a specified number of times.
• ♾️ Forever Loop: Executes a block of code indefinitely (until the program is stopped).
• ⏱️ Repeat Until Loop: Executes a block of code until a specified condition is true.
• 🛑 Stopping Forever Loops: Usually requires a condition inside the loop to break it, or manual program termination.
• 💡 Use Cases: Repeat loops are great for animations or actions that need to happen a set number of times. Forever loops are perfect for continuous processes, like checking for user input.
