 ## Curly Braces
 Functions shall have the opening brace at the beginning of the next line.
+```
+int function(int x)
+{
+    body of function
+}
+```
 
 All non-function statement blocks (if, switch, for) shall have the opening brace last on the same line, with the following statement on the next line.
 
 Closing braces shall be but on the line after the last statement in the block.
+```
+if (x is true) {
+    we do y
+    ...
+}
+```
+
+```
+switch (action) {
+    case ADD:
+        return "add";
+    case REMOVE:
+        return "remove";
+    case CHANGE:
+        return "change";
+    default:
+        return NULL;
+}
+```
 
 If it is followed by an `else` or `else if` that shall be on the same line, again with the opening brace on the same line.
+```
+if (x is true) {
+    we do y
+    ...
+} else {
+    we do z
+    ...
+}
+```
 
 A single statement after an `if` or an `else` may omit the "unnecessary" braces only when ALL conditional branches have single statements AND you have strong reason to know it will always be that way.
+```
+if (x is true)
+    we do y
+else
+    we do z
+```
+
+```
+if (x is true) {
+    we do y
+    ...
+} else {
+    we do z
+}
+```
 
 If in doubt, do not omit such "unnecessary" braces.
 (Adding a statement to a branch will break the logic if the braces are forgotten and otherwise make the PR longer).
