This rule finds comparison expressions that use 2 or more comparison operators and are not completely parenthesized. It is best to fully parenthesize complex comparison expressions to explicitly define the order of the comparison operators.

voidh(){inta,b,c;a<b!=c;//parenthesize to explicitly define order of operators(a<b)<c;//correct: parenthesized to specify order}
