5 -1 Logical Data and Operators A piece of data is called logical if it conveys the idea of true or false. In real life, logical data (true or false) are created in answer to a question that needs a yes–no answer. In computer science, we do not use yes or no, we use true or false.

5 -2 Two-Way Selection The decision is described to the computer as a conditional statement that can be answered either true or false. If the answer is true, one or more action statements are executed. If the answer is false, then a different action or set of actions is executed. Topics discussed in this section: if…else and Null else Statement Nested if Statements and Dangling else Problem Simplifying if Statements Conditional Expressions Computer Science: A Structured Programming Approach Using C 9

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.

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, C 99 has two parallel but separate header files for manipulating characters: ctype. h and wctype. h.
