Summary

Chapter five explores conditionals and logic. It begins by introducing the relational operators. Relational operators, as you will see, evaluate to true or false. The chapter then discusses logical operators. Logical operators allow you to join multiple relational expressions together to form more complex expressions. The chapter then combines relational operators and logical operators for using them in conditional statements. The chapter ends by presenting simple recursion.
