How is syntax defined in the context of programming languages?

In programming languages, syntax refers to the set of rules that defines the structure of statements in that language. It dictates how symbols, keywords, and other elements can be combined to form valid instructions that a computer can understand. Just like grammar in human languages, syntax ensures that code is written in a way that the programming language interpreter or compiler can correctly interpret and execute.

Understanding syntax is vital for any programmer because it determines how the code must be formatted, including aspects such as punctuation, indentation, and the proper use of functions and variables. If the syntax is incorrect, the code will not compile or run, leading to syntax errors. Therefore, recognizing that syntax encompasses the grammar rules for writing statements is essential for effectively coding in any programming language.
