What happens when a syntax error is present in the code?

When a syntax error is present in the code, the program does not compile. A syntax error occurs when the rules of the programming language are violated, such as missing punctuation, misspelled keywords, or incorrect use of language constructs. These errors prevent the code from being successfully translated from source code into an executable program. Since compilation is a necessary step before execution, the presence of a syntax error halts this process, making it impossible for the program to run until the error is corrected. This is a fundamental aspect of programming, as it ensures that only syntactically correct code is processed for execution.
