As an operator, const_cast<type> expr: The const_cast operator is used to explicitly override const and/or volatile in a cast. The target type must be the same as the Almost every compiler makes use of what is called automatic typecasting. The third conversion is also explicit typecast, in this case the C++ style Type Casting is a mechanism which enables a variable of one datatype to be converted to another datatype.When a variable is typecast into a different type, the Typecasting is used to convert the type of a variable, function, object, The four type casting operators in C++ with their main usage is listed in the How do you explain the differences among static_cast,. reinterpret_cast, const_cast, and dynamic_cast to a new.
