Any language expression consists of operands (variables, constants, etc.) connected with each other by operators. Operations are executed in a strict order. The value that determines a privilege to execute a certain operation is called precedence. The op
↑ The expression in the middle of the conditional operator (between ? and :) is parsed as if parenthesized: its precedence relative to ?: is ignored. ↑ Assignment operators' left operands must be unary (level-2 non-cast) expressions. This rule grammatically forbids some expressions that woul...

這個警告表示可能發生運算子優先順序 (Operator Precedence) 的問題。'+'、'-'、'*' 及 '/' 運算子的優先順序高於 '?' 運算子。如果運算式中的優先順序不正確,請使用括號變更運算子的優先順序。 範例 下列程式碼將產生出這個警告: int Count(); void f(int flag) { int result; result = Count() + ...
