However, if you cast away the constness of an object that has not been explicitly declared as const, you can modify it safely. In the above example, the object referred to by b1 has not been declared const, but you cannot modify this object through b1. You may cast away the constness ...
The first choice that satisfies the requirements of the respective cast operator is selected, even if it is ill-formed (see example). If astatic_castfollowed by aconst_castis used and the conversion can be interpreted in more than one way as such, the conversion is ill-formed. ...
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 1. 转...
This document identifies common type conversion problems and describes how you can avoid them in your C++ code.When you write a C++ program, it's important to ensure that it's type-safe. This means that every variable, function argument, and function return value is storing an acceptable ...

Overloading Operator Type() IN class If you create a class, it could have overloaded operator (). So, if you need to use implicit conversion, it could be achieved with constructor that is used for initialization, and if you are having the problems with this, you could define explicit con...
variable, because we rarely intend to lose data in such cases. But when using a cast, it is presumed we know what we’re doing, and if we want to do a cast that might lose some data, we should be able to do that. The narrowing conversion restriction can be an impediment in this ...
in the parameter list of a function (when the parameter name is omitted), type-id uses decl-specifier-seq instead of type-specifier-seq (in particular, some storage class specifiers are allowed); in the name of a user-defined conversion function, the abstract declarator cannot include ...
When converting from one non-class type to another non-class type, only a standard conversion sequence is allowed. (https://en.cppreference.com/w/cpp/language/implicit_conversion) Basically, after Dollar is converted to std::string, the compiler sees that, somewhere down the line (depending ...
