One-Dimensional Arrays

Abstract

Recall that abstraction involves the suppression of detail. The collection of a group of items is generally the first step toward abstraction. The previous chapter presented proper procedures and function procedures, which are collections of program statements executed when one procedure calls another. Declaring a procedure creates a new statement that the calling procedure can use. One advantage of such declarations is that if different people design the calling procedure and the called procedure, the person who writes the calling procedure does not need to know about the collection of statements in the called procedure. This is particularly true when the called procedure is in a different module from the calling procedure. The collection of statements is a step toward program abstraction.
