Summary

Chapter 5 introduces perhaps the most difficult tools for new programmers to grasp, namely conditionals and loops, which control when, whether, and how often code executes. Presentation of conditionals and loops begins with descriptions of what they do: conditionals control whether code runs, or which piece of code runs from multiple options; while loops make code run repeatedly, either “while” some condition is met (“while” loops) or “for” each element of a set of values (“for” loops). This presentation makes clear to students how to translate these descriptions into MATLAB code, allowing them to see the correspondences between the broader programming task and the tools that accomplish them. Syntax is explored in detail, including common pitfalls and specification errors. Lastly, syntax for interrupting loops and changing their operation is presented, furthering students’ mastery of these critical tools.

Summary

In this chapter the reader creates if statements, which include elif and else statements, and learns about nesting statements together. They become familiar with conditional operators such as greater than, less than and equal to along with comparison operators such as and, or and not as they build upon the knowledge they have acquired in the first chapter to program solutions for the eight given challenges.
