Static cast conversion cppreference, 2 If target type is an rvalue reference type and the referenced type is reference compatible with the type of expression static cast converts the value of glvalue class prvalue or array prvalue until C 17 any lvalue since C 17 expression to xvalue referring to the same object as the expression or to its base sub object depending on
Dynamic cast conversion cppreference
If the cast is successful dynamic cast returns a value of type target type If the cast fails and target type is a pointer type it returns a null pointer of that type If the cast fails and target type is a reference type it throws an exception that matches a handler of type std bad cast ExplanatioFor the convenience of description expression or the result is a reference to T means

Const cast conversion cppreference
Const cast conversion cppreference, 2 For two object types T1 and T2 if a pointer to T1 can be explicitly converted to the type pointer to T2 using const cast T2 then the following conversions can also be made An lvalue of type T1 can be explicitly converted to an lvalue of type T2 using const cast T2 A glvalue of type T1 can be explicitly converted to an xvalue of type T2 using const cast T2

Reinterpret cast conversion cppreference
Reinterpret cast conversion cppreference Only the following conversions can be done with reinterpret cast except when such conversions would cast away constness or volatility An expression of integral enumeration pointer or pointer to member type can be converted to its own type The resulting value is the same as the value of A pointer can be converted to any integral type
