That is why it is equal for every pointer type for same operating system and CPU architecture. User-Defined Data Types The user-defined data types are the data types that are defined by the programmers in their code. the expression is an unevaluated operand)(since C++11), and even if the expression designates a polymorphic object, the result is the size of the static type of the expression. It is an operator whose value is determined by the compiler; for this reason, it is referred to as a compile-time unary operator. The result of sizeof is always nonzero, even if applied to an empty class type. We can easily determine that to find the size of the pointer in C, the operand must be a pointer.
