  1. 5-3 Multiway Selection In addition to two-way selection, most programming languages provide another selection concept known as multiway selection. Multiway selection chooses among several alternatives. C has two different ways to implement multiway selection: the switch statement and else-if construct. Topics discussed in this section: The switch Statement The else-if Computer Science: A Structured Programming Approach Using C

  14. Note The else-if is an artificial C construct that is only used when 1. The selection variable is not an integral, and 2. The same variable is being tested in the expressions. Computer Science: A Structured Programming Approach Using C

  18. 5-4 More Standard Functions One of the assets of the C language is its rich set of standard functions that make programming much easier. For example, C99 has two parallel but separate header files for manipulating characters: ctype.h and wctype.h.
