We include a specialization for it in case it is signed. We are now ready to write a template class with a static method, and partial specializations for cases where the parameters differ in signedness.

WebMar 11, 2024 · Static Cast This is the simplest type of cast that can be used. It is a compile-time cast. It does things like implicit conversions between types (such as int to float, or pointer to void*), and it can also call explicit conversion functions. Syntax: static_cast (source); The return value of static_cast will be of dest_type. Example: WebJan 13, 2009 · int and unsigned int have the same size. If a number doesn't fit in int, it won't fit in unsigned integer, either (e.g. 2^31 can be assigned to a 32-bit signed int without data loss). Pointers may be of a different size than int. For example, Borland C++ uses (last time I checked) 16-bit ints.
