2️⃣ Typecasting on nullptr_t A cast of nullptr_t to an integral type needs a reinterpret_cast, and has the same semantics as a cast of (void*)0 to an integral type. Casting nullptr_t to an integral type holds true as long as destination type is large enough. Consider this: /...
The general form for defining an array is type array_name[size]; Here, type specifies the data type of each element of the array, followed by the name of the array array_name. The size specifies the maximum number of elements that can be stored in an array. The size must be an ...
What is a user-defined data type? A user-defined data type (UDT) is a data type that a user can define and derive from an existing data type. Many UDTs have the same internal representation as built-in or source data types. These distinct UDTs increase the number of data types availabl...
Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it…

the Visual C++ compiler did not provide this in specific casting scenarios. A new compiler option, /Zc:rvalueCast, has been added to make the compiler conformant with the C++ Language Working Paper(see section 5.4, [expr.cast]/1). The default behavior when this option is not specified is...
