Multiple Choice Questions on 'Forever' and 'Repeat' Loops

📚 Quick Study Guide

• ♾️ A 'forever' loop, also known as an infinite loop, continues indefinitely until a specific condition is met to break the loop.
• 🔁 A 'repeat' loop, often called a 'for' loop or a 'while' loop with a defined ending condition, executes a block of code a specific number of times or until a condition becomes false.
• 🚦 Key Difference: 'Forever' loops require a manual 'break' statement or condition to stop, while 'repeat' loops have a built-in mechanism to terminate.
• ⏱️ 'Repeat' loops are useful when you know in advance how many times you need to execute a piece of code.
• 🚨 Be cautious with 'forever' loops; ensure there's a way to exit them to prevent program crashes.
