In this talk we will build a refined and improved definition of undefined behavior, to motivate and encourage C++ developers to write correct code. We will explain the terminology associated with Undefined Behavior and explore why it exists in the C++ language. Looking at the standard is the only way to determine what constitutes undefined behavior.
During this talk we will present several new examples to illustrate how various types of undefined behavior can occur in a short span of code. We will also describe the various categories of behavior and the difference between run time errors and undefined behavior. Understanding these distinctions is critical to being an effective programmer.
This talk is part of the Back to Basics track and the material will be targeted to include all skill levels. Familiarity with C++ is recommended however no prior knowledge of compilers or undefined behavior is required.
