EXP62-CPP-EX1: It is permissible to access the bits of an object representation when that access is otherwise unobservable in well-defined code. For instance, it is acceptable to call std::memcpy() on an object containing a bit-field, as in the following example, because the read and write of the padding bits cannot be observed. However, the code must still comply with OOP57-CPP. Prefer special member functions and overloaded operators to C Standard Library functions.

#include <cstring>
 
struct S {
  int i : 10;
  int j;
};
 
void f(const S &s1) {
  S &s2;
  std::memcpy(&s2, &s1, sizeof(S));
}
