2.3 Iteration

2.3.1 for Loops

1. - The way statements are sequenced and combined in a program determines the computed result. Programs incorporate iteration and selection constructs to represent repetition and make decisions to handle varied input values.

1. - How can we store data in a program to solve problems?
  - What might happen if you completed the steps in your regular morning routine to get ready and go to school in a different order? How might the reordering affect the decisions you make each morning?
  - How do video games group different actions for a player based on what key is pressed on the keyboard or controller? How do apps group different actions together based on user interaction, such as pressing buttons?
  - What types of problems can be solved more easily with a computer, and what types can be solved more easily without a computer? Why?

Iteration is a repeating portion of an algorithm. Iteration repeats a specified number of times or until a given condition is met.
Iteration statements change the sequential flow of control by repeating a set of statements zero or more times, until a stopping condition is met.
