Real-Life Examples of If/Else Logic in Everyday Scenarios

📚 Quick Study Guide

• 🚦 If/Else Basics: The 'if' statement checks a condition. If the condition is true, a block of code runs. Otherwise (the 'else' part), a different block of code runs.
• ⌚ Real-World Analogy: Think of a thermostat. IF the temperature is below the set point, THEN turn on the heater. ELSE, turn off the heater.
• 💻 Code Example: In Python: python temperature = 20 if temperature < 22: print("Turn on the heater") else: print("Turn off the heater")
• 🔑 Key Concept: Only ONE of the blocks of code (either the 'if' block OR the 'else' block) will execute. Never both.
• 🧮 Nested If/Else: You can have 'if/elif/else' structures for more complex decisions, checking multiple conditions in sequence.
