🧠 Quick Study Guide: 'If' Statements
- 💡 An 'if' statement is a fundamental programming construct that allows a program to make decisions.
- ❓ It checks if a specific condition is true or false.
- ✅ If the condition is true, a certain block of code inside the 'if' statement will execute.
- ❌ If the condition is false, the code inside the 'if' block is skipped.
- ➡️ Think of it like a fork in the road: 'If' the path is clear, you go one way; otherwise, you don't.
- ✨ 'If' statements are the building blocks for creating dynamic and responsive programs.
