What is 'syntax' in programming?

In programming, syntax refers to the specific set of rules and guidelines that dictate how code must be written in a particular programming language. This includes the correct arrangement of symbols, keywords, and other elements that are necessary to form valid statements. Correct syntax is crucial because it ensures that the code can be understood and executed by the computer without errors.

For instance, just as sentences in natural languages need to follow grammatical rules to make sense, programming languages require strict adherence to syntax to function correctly. When programmers adhere to the syntax of a language, it allows for clear communication of instructions, leading to successful program compilation and execution.
