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() + ...
When you define a macro, you request concatenation with the special operator`##'in the macro body. When the macro is called, after actual arguments are substituted, all`##'operators are deleted, and so is any whitespace next to them (including whitespace that was part of an actual argument...

In C++, the conditional operator has the same precedence as assignment operators, and prefix ++ and -- and assignment operators don't have the restrictions about their operands. Associativity specification is redundant for unary operators and is only shown for completeness: unary prefix operators al...

When the tcsh shell's input is not a terminal, the character '#' is taken to begin a comment. Each # and the rest of the input line on which it appears is discarded before further parsing. A special character (including a blank or tab) can be prevented from having its special meaning...
Many runtime verification tools are built based on Aspect-Oriented Programming (AOP) tools, most often AspectJ, a mature implementation of AOP for Java. Although already popular in the Java domain, there is few work on runtime verification of C programs
