The C++ standard does not say how much memory should be used for the int type, it just says how much memory should be at least used for the int type. For example, the int type is generally stored in four bytes, but this is not always true, on a few implementations it is stored in two bytes.
Education Requirements for an RN. There are generally three educational approaches to becoming a RN. RNs usually train by completing a bachelor's or associate's degree program in nursing. Less commonly, RNs prepare for the occupation by earning a diploma in nursing.
Educational Requirements for Registered Nurses. Nursing students may choose from a variety of education options to become a registered nurse. Some teaching hospitals offer 3-year diploma programs in nursing; however, these programs are rare. Most RNs earn associate degrees or bachelor's degrees in nursing.
