New in the C23 standard, thetypeofoperator is a unary operator that returns the type of an expression. It can be used in type declarations, type casts, type checks, and so on. It gets the type of a variable, function, or any C expression. ...
类型转换操作符(type conversion operator)是一种特殊的类成员函数,它定义将类类型值转变为其他类型值的转换。转换操作符在类定义体内声明,在保留字 operator 之后跟着转换的目标类型。boost::ref和boost::cref就使用到了类型转换操作符。 函数原型 T1::operatorT2()const;//T1的成员函数,"(T2)a"类型转换 ...
