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.
Step 1: Graduate from High School. A high school education is an essential prerequisite to becoming a registered nurse. Coursework in biology, psychology, mathematics and English is helpful. Advanced placement classes in anatomy and physiology can be especially beneficial.tep 3: Become Licensed. All states require registered nurses to pass the National Council Licensure Examination (NCLEX-RN), which is administered by the National Council of State Boards of Nursing (www.ncsbn.org).
