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.
To become a nurse, you must first achieve certification as a registered nurse (RN). To do that, the first step is to earn a Bachelor of Science in Nursing (BSN) degree. While you may also choose to earn a nursing diploma or associate degree, which takes three years, a BSN will make it easier for you to find a job.
