Question

Can we cast an object with user-defined types, like we do for normal data types?
Like say we do type cast for int like:

int variable_one = (int)variable_name;

So can we do like: (complex) object_name;
where complex is the class I have written for complex number addition using operator+ overloading.

Is it possible in this normal way? Or do we need to write some function before calling this statment? Or is it not possible at all to type-cast like this?

Answer 1

int variable_one=(int)variable_name; is a C style cast.

C++ offers many casting operators:

• dynamic_cast <new_type> (expression)
• reinterpret_cast <new_type> (expression)
• static_cast <new_type> (expression)
• const_cast <new_type> (expression)

Have a look at article about type casting or refer to any C++ introductory book.
