Operator precedence is unaffected byoperator overloading. For example,std::cout<<a?b:c;parses as(std::cout<
See operator precedence for the details on the relative precedence of this operator and assignment. Conditional operator has right-to-left associativity, which allows chaining Run this code #include <assert.h> enum vehicle { bus, airplane, train, car, horse, feet }; enum vehicle choose(char...

↑ sizeof 的运算数不能是转换: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 级非转换)表达式。此规则在文法上禁止某些表...
