'In order to avoid such implicit conversions, a constructor that takes one argument needs to be declared explicit: class string { //... public: explicit string(int size); // block implicit conversion string(const char *); //implicit conversion ~string(); }; An explicit constructor does no...
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/cpp/language...

The error message “ERROR due to explicit (no implicit type conversion allowed)” indicates that there is a type mismatch or incompatible types in your code, and an explicit type conversion is required to resolve it. In C++, explicit type conversions are performed using explicit casting operators...
