+# 字符、布尔、单元类型
+
+### 字符
+🌟
+```rust
+
+use std::mem::size_of_val;
+fn main() {
+    let c1 = 'a';
+    assert_eq!(size_of_val(&c1),1); 
+
+    let c2 = '中';
+    assert_eq!(size_of_val(&c2),3); 
+} 
+```
+
+🌟
+```rust
+
+fn main() {
+    let c1 = "中";
+    print_char(c1);
+} 
+
+fn print_char(c : char) {
+    println!("{}", c);
+}
+```
+
+### 布尔
+🌟
+```rust
+
+// 让  println! 工作
+fn main() {
+    let _f: bool = false;
+
+    let t = true;
+    if !t {
+        println!("hello, world");
+    }
+} 
+```
+
+🌟
+```rust
+
+fn main() {
+    let f = true;
+    let t = true && false;
+    assert_eq!(t, f);
+}
+```
+
+
+### 单元类型
+🌟🌟
+```rust
+
+// 让代码工作，但不要修改 `implicitly_ret_unit` !
+fn main() {
+    let _v: () = ();
+
+    let v = (2, 3);
+    assert_eq!(v, implicitly_ret_unit())
+}
+
+fn implicitly_ret_unit() {
+    println!("I will returen a ()")
+}
+
+// 不要使用下面的函数，它只用于演示！
+fn explicitly_ret_unit() -> () {
+    println!("I will returen a ()")
+}
+```
+
+🌟🌟 单元类型占用的内存大小是多少？
+```rust
+
+// 让代码工作：修改 `assert!` 中的 `4` 
+use std::mem::size_of_val;
+fn main() {
+    let unit: () = ();
+    assert!(size_of_val(&unit) == 4);
