Traversing, Analyzing, and Generating Sequences of Data

When a program visits each element of a list of elements, programmers say the list is being traversed. Traversal is one of the most fundamental uses of iteration statements. The general loop construct for analyzing a list of data can be depicted by a flow chart or pseudocode as in Figure 9.1. Notice how the depiction matches our definition of an iteration statement presented in the beginning of the previous chapter: “An iteration statement repeats a statement or a block of statements until a given termination condition is met.”
