Which type of error is a syntax error?

A syntax error refers to a mistake that occurs when the rules and structure of the programming language are not followed. This type of error prevents the code from being compiled or interpreted correctly. For example, forgetting a semicolon at the end of a statement, misplacing parentheses, or using an invalid character can all lead to syntax errors. Because these errors violate the grammatical rules of the programming language, they must be corrected before the program can be successfully executed.

In contrast, other types of errors such as logical errors occur when the program runs without crashing but produces incorrect results due to flaws in the program's logic. Run-time errors are issues that occur while the program is executing, such as attempting to divide by zero or accessing an out-of-bounds index in an array. Misused operators can lead to logical or syntax errors, depending on the context. However, only those errors that specifically involve the misconfiguration of the language's grammar or structure qualify as syntax errors.
