What is the definition of syntax in programming?

The definition of syntax in programming refers specifically to the sentence structure of a programming language. Each programming language has its own set of rules that dictate how code must be written for it to be understood and executed correctly by the computer. These rules include the proper arrangement of keywords, operators, and punctuation in the code. Just as grammar dictates how sentences are constructed in human languages, syntax governs the structure of code in programming. If the code does not adhere to these syntactical rules, it will lead to errors and prevent the program from running as intended. Understanding syntax is crucial for writing valid and functional code in any programming language.
