Characteristics of Identifiers in Programming

Identifiers have special characteristics in programming languages. Some of them are:

• They must follow the naming rules specified by the programming language, typically starting with a letter, underscore, or certain special characters, followed by letters, digits, or underscores.
• Identifiers are often case-sensitive, distinguishing between uppercase and lowercase letters.
• They cannot be the same as reserved words or keywords predefined by the programming language.
• Good programming practice dictates that identifiers should be meaningful and descriptive, reflecting the purpose or meaning of the associated program element.

Identifiers are names given to various programming elements, such as variables, functions, classes, constants, and labels. They serve as labels or handles that programmers assign to program elements, enabling them to refer to these elements and manipulate them within the code. In this article, we will learn about the basics of Identifiers, and its use cases.
