  • 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.
