Daily Life Magazine wants an analysis of the demographic characteristics of its readers. The marketing department has collected reader survey records containing the age, gender, marital status, and annual income of readers. Design an application that allows a user to enter reader data and, when data entry is complete, produces a count of readers by age groups as follows: younger than 20, 20-29, 30-39, 40-49, and 50 and older.

Explanation:
