+# `if` Expressions
+
+![bg right:25% 75%](./images/ferris_does_not_compile.svg)
+
+`if` expressions must condition on a boolean expression.
+
+```rust
+fn main() {
+ let number = 3;
+
+ if number {
+ println!("number was three");
+ }
+}
+```
+
+```
+error[E0308]: mismatched types
+ --> src/main.rs:4:8
+ |
+4 | if number {
+ | ^^^^^^ expected `bool`, found integer
+```

+
+
+# Matches Are Exhaustive
+
+![bg right:25% 75%](../images/ferris_does_not_compile.svg)
+
+The `match` patterns must cover all possible values that the matched expression may take.
+
+What happens when we miss a case?
+
+```rust
+let x: i8 = 5;
+let y: Option = Some(5);
+
+let sum = match y {
+ Some(num) => x + num,
+};
+```
+

+
+
+# Matches Are Exhaustive
+
+```rust
+let x: i8 = 5;
+let y: Option = Some(5);
+
+let sum = match y {
+ Some(num) => x + num,
+};
+```
+
+```
+error[E0004]: non-exhaustive patterns: `None` not covered
+ --> src/main.rs:6:21
+ |
+6 | let sum = match y {
+ | ^ pattern `None` not covered
+```
+
+* Forces us to explicitly handle the `None` case
+* Protecting us from the billion-dollar mistake!
