sql - datetime Cast or Convert? - Stack Overflow 10 convert has an optional parameter style, and I suggest to use convert instead of cast It helps to avoid confusion For example, if you write cast('20130302' as date), what would you get? March 2 or February 3? Also, if you want specific format when casting to date to string, you bound to use convert
What are the rules for casting pointers in C? - Stack Overflow There are rules about casting pointers, a number of which are in clause 6 3 2 3 of the C 2011 standard Among other things, pointers to objects may be cast to other pointers to objects and, if converted back, will compare equal to the original
casting - Explanation of ClassCastException in Java - Stack Overflow 6 Do you understand the concept of casting? Casting is the process of type conversion, which is in Java very common because its a statically typed language Some examples: Cast the String "1" to an int, via Integer parseInt("1") -> no problem Cast the String "abc" to an int -> raises a ClassCastException
Regular cast vs. static_cast vs. dynamic_cast - Stack Overflow Static cast is also used to cast pointers to related types, for example casting void* to the appropriate type dynamic_cast Dynamic cast is used to convert pointers and references at run-time, generally for the purpose of casting a pointer or reference up or down an inheritance chain (inheritance hierarchy) dynamic_cast (expression)
c++ - When should static_cast, dynamic_cast, const_cast, and . . . The C-style casts can do virtually all types of casting from normally safe casts done by static_cast<> () and dynamic_cast<> () to potentially dangerous casts like const_cast<> (), where const modifier can be removed so the const variables can be modified and reinterpret_cast<> () that can even reinterpret integer values to pointers
What is the difference between static_cast lt; gt; and C style casting? See A comparison of the C++ casting operators However, using the same syntax for a variety of different casting operations can make the intent of the programmer unclear Furthermore, it can be difficult to find a specific type of cast in a large codebase the generality of the C-style cast can be overkill for situations where all that is needed is a simple conversion The ability to select
