Boolean Naming Convention
Boolean naming convention
Boolean, in programming, is a data type that is either true or false. Prefixes like is, has, and are added in the booleans to distinguish them from other variables. Boolean data-type has two values true or false.
Note We will discuss booleans in more detail in the upcoming chapters.
