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.
The two most common ways to become a registered nurse are to get a bachelor of science degree in nursing (BSN) or an associate's degree in nursing (ADN). A BSN takes about four years to complete at a college or university. An ADN program at a community or junior college takes about two to three years.
