The current table gives more information and is more readable than the one at operator-precedence.com. The colors they chose to categorize the operators are hardly distinguishable, using brighter colors would make the page look very messy.
Operator precedence is unaffected byoperator overloading. For example,std::cout<<a?b:c;parses as(std::cout<
Operatoren, die in derselben Zelle gelistet sind (es können auch mehrere Operatoren in einer Zelle aufgeführt sein), werden mit gleicher Priorität in der angegebenen Auswertungsrichtung ausgewertet. Beispielsweise wird der Ausdruck a=b=c aufgrund der Assoziativität von-rechts-nach-li...

↑ sizeof 的运算数不能是类型转型:表达式 sizeof (int) * p 无歧义地转译成 (sizeof(int)) * p ,而非 sizeof((int)*p)。 ↑ 条件运算符中部(? 与: 之间)的表达式分析为如同加括号:忽略其相对于 ?: 的优先级。 ↑ 赋值运算符的左运算数必须是一元(第 2 级非转型)表达式。此规则在文法上禁止某...
The precedence of these operators is the same as that for C. In addition, the unary operator defined, can be used in constant-expression in these two forms: `defined ( name )' or `defined name'. This allows the effect of #ifdef and #ifndef directives (described below) in the #if dir...
