Keywords serve as instructions to the compiler/interpreter, guiding it in analyzing and executing the program correctly. This limited set helps maintain consistency and avoids clashes with user-defined names.Ĭompiler/Interpreter Recognition: The compiler or interpreter of a programming language recognizes keywords during the parsing phase of execution. Limited in Number: Programming languages have a finite set of keywords, and the number of keywords is relatively small compared to the total number of available identifiers. These meanings are consistent across all implementations of the programming language, ensuring portability and standardization. For example, 'if' and 'IF' are distinct keywords in C, and using them interchangeably may lead to syntax errors.įixed Meaning: Each keyword has a specific purpose and a well-defined meaning within the language. They are part of the language's syntax and cannot be used as variable names, function names, or any other user-defined identifiers within the C program.Ĭase-Sensitive: Keywords are case-sensitive, meaning that uppercase and lowercase letters are treated differently. Reserved: Keywords are reserved by the programming language and have predefined meanings. Here are some notable properties of keywords:
Keywords in programming languages like C possess certain properties that differentiate them from regular identifiers. They are used to define control structures, data types, function declarations, and other fundamental elements of C programming. These keywords in C have specific meanings. As of the C99 standard, there is a set of 32 keywords in C language, as shown in the table below. How Many Keywords Are There In C?Ĭ has a relatively small set of keywords compared to some other programming languages. The C language keywords are case-sensitive, meaning that uppercase and lowercase letters are treated differently. These words are reserved by the language and cannot be used as variable names or any other identifiers. Keywords, also known as reserved words, are predefined identifiers in a programming language that have special meanings and purposes. In this article, we will explore the significance of keywords in C, an integral part of the language, and provide insights into their usage.

Understanding this powerful tool's fundamentals can benefit anyone interested in improving their programming skills or developing advanced software solutions. This versatile language can be used for various purposes, from creating basic programs like word processors and calculators to more complex applications such as artificial intelligence systems. With technological advances, it is becoming increasingly important to understand and use one of the most important computer programming languages C.
