+*  Always use curly braces, even when there is only one instruction. Instead of
+<c>if (a) do_something();
+</c>
+write
+<c>if (a) {
+	do_something();
+}</c>
+* Place opening brace at the same line as the condition as in
+<c>while (expr) {
+}
+for (;;) {
+}

+unless the expression is very long as in
+<c>if

+* Surround else with braces as in
+<c>if (expr) {

+} else {
+	...
+}
+</c>
+* Avoid using assignment inside an expression.
