 Try to make it "look good" by drawing a vertical line at 40 columns and
 "balancing" characters on either side. This is a subjective rule.
 
-## Type declarations
+## Struct and union declarations
+
+Programmers **MUST** declare structs and unions with the `{` on the first line,
+and `};` on its own line.
+
+Correct:
+
+```c
+struct my_struct {
+    int field_a;
+    int field_b;
+    int field_c;
+};
+
+union my_union {
+    int i;
+    long l;
+    double d;
+};
+```
+
+Incorrect:
+
+```c
+struct my_struct
+{
+    int field_a;
+    int field_b;
+    int field_c;
+};
+
+union my_union
+{
+    int i;
+    long l;
+    double d;
+};
+```
+
+Programmers **MUST** place the name of an inline struct or union field on the
+same line as `}` and `;`.
+Correct:
+
+```c
+struct my_struct {
+    struct {
+        int a, b,c;
+    } nested_struct;
+
+    union {
+        int a, b,c;
+    } nested_union;
+};
+```
+
+Incorrect:
+
+```c
+struct my_struct {
+    struct {
+        int a, b,c;
+    }
+    nested_struct;
+
+    union {
+        int a, b,c;
+    }
+    nested_union;
+};
+```
+
+## Variable declarations
 
 Programmers **MUST place \* next to the binding when declaring pointers.**
