C + + provides 4 type-to operators, namely: Static_cast, dynamic_cast, reinterpret_cast, and const_cast;The syntax format is as follows:Type conversion Operators (expreession);Description: TYPE_ID is the target type; expression is the original data.

C++A reference reference variable is an alias, that is, it is another name for an existing variable. Once the reference is initialized to a variable, you can use that reference name or variable name to point to the variable. C++reference vs pointer
