This chapter introduces the C# constructs that choose different code paths: `if`, `else if`, `else`, `switch`, and the Boolean expressions that control them.\n\n- **Boolean expressions**: Conditions evaluate to `true` or `false` and drive program decisions.\n- **`if` statements**: An `if` statement runs code only when its condition is true.\n- **Multi-branch logic**: `else if`, `else`, and `switch` handle several possible cases.\n- **Logical operators**: Operators such as `&&`, `||`, and `!` combine or reverse conditions.\n\nConditionals let programs validate input, express business rules, and respond differently as data changes.\n"

Construct Boolean expressions with comparison and logical operators\n3. Handle multiple exclusive cases with a `switch` statement\n4. Trace which branch of a conditional statement will execute\n5. Avoid common conditional mistakes such as dangling `else` and boundary errors\n"
