Day 7. More on Program Flow
Today, you will learn
• What loops are and how they are used
• How to build various loops
• An alternative to deeply nested
Many programming problems are solved by repeatedly acting on the same data. Two ways to do this are recursion (discussed on Day 5, “Organizing into Functions”) and iteration. Iteration means doing the same thing again and again. The principal method of iteration is the loop.
The Roots of Looping:
In the primitive days of early computer science, programs were nasty, brutish, and short. ...
