Real-Life Examples of While Loops: Iteration in Everyday Applications

📚 Quick Study Guide

• 🔄 A `while` loop repeatedly executes a block of code as long as a specified condition is true.
• 💡 The condition is checked at the beginning of each iteration. If the condition is false initially, the loop body will not execute.
• ⏱️ Ensure the loop condition eventually becomes false to avoid infinite loops.
• ➕ Common uses include iterating until a certain value is reached, processing data until no more is available, and game loops.
• 🔢 Syntax: `while (condition) { // code to be executed }`
