The correct answer is: Syntax.
The syntax of a programming language is the set of rules that govern the structure of valid programs in that language. It defines how tokens (sequences of characters) are combined to form phrases, how phrases are combined to form statements, and how statements are combined to form programs.
The rules of a programming language are called its syntax because they define the structure of valid programs. The syntax of a programming language is typically defined in a formal grammar, which is a set of rules that specify how the tokens of the language can be combined to form valid programs.
The syntax of a programming language is important because it ensures that programs are well-formed and can be interpreted or compiled correctly. If a program does not follow the rules of the language’s syntax, it will be considered invalid and will not be able to be executed.
The other options are incorrect because they do not accurately describe the rules of a programming language.
- Rules is a general term that could refer to any set of rules, not just the rules of a programming language.
- Grammar is a specific term that refers to the rules of a language, but it can refer to the rules of any language, not just a programming language.
- Order is not a technical term that is used to describe the rules of a programming language.
