- Always use curly braces, even when there is only one instruction. Instead of
if (a) do_something();
write
if (a) { do_something(); }
- Place opening brace at the same line as the condition as in
while (expr) { } for (;;) { }
unless the expression is very long as in
if (very_long_expression) { ... }
- Surround else with braces as in
if (expr) { ... } else { ... }
- Avoid using assignment inside an expression.
