3.explicit 参考https://zh.cppreference.com/w/cpp/language/explicit 与隐式转换对应出现的就是explicit关键字,既然提供了隐式转换,那么肯定也有禁止隐式转换的方法。explicit关键字就是声明在构造函数前,明确指定,不允许隐式转换构造,必须是明确的 4.user-defined conversion 参考https://en.cppreference.com/w/...
Implicit conversion sequence consists of the following, in this order: 1)zero or onestandard conversion sequence; 2)zero or oneuser-defined conversion; 3)zero or onestandard conversion sequence(only if a user-defined conversion is used).
In a return statement, the value of the operand of return is converted to an object having the return type of the function Note that actual assignment, in addition to the conversion, also removes extra range and precision from floating-point types and prohibits overlaps; those characteristics do...
