+# `.h` and `.cc` files come in pairs

+<?% config.freshness.owner = 'danilchap' %?>
+<?% config.freshness.reviewed = '2021-05-12' %?>
+
+This is an overflow page for [this](../style-guide.md#h-cc-pairs)
+style rule.
+
+## Example violations
+
+Example violations, which should be avoided in new code:
+
+* Declarations in `path/to/include/foo.h`, definitions in
+  `path/to/source/foo.cc`. **Fix:** The `.h` and `.cc` files should be
+  in the same directory.
+* Declarations in `foo.h`, definitions in both `foo_bar.cc` and
+  `foo_baz.cc`. **Fix:** The `.h` and `.cc` files should come in
+  pairs, so either split `foo.h` into `foo_bar.h` and `foo_baz.h`, or
+  merge `foo_bar.cc` and `foo_baz.cc` into `foo.cc`.
+
+## Exception for platform-specific code
+
+If the functions in a header file need different implementations for
+different platforms, we allow the following arrangement:
+
+* Declarations in `foo.h`.
+* A complete set of matching definitions in `foo_win.cc`, another
+  complete set of matching definitions in `foo_mac.cc`, and so on.
+* As per the main rule, these files should all be in the same
+  directory and in the same build target. The build target should use
+  platform conditionals to ensure that exactly one of the `.cc` files
+  are included.
