What is a false statement about syntax errors?

A false statement about syntax errors is that they indicate issues with array size matching. Syntax errors specifically arise from incorrect use of the programming language's syntax, including misplaced operators, missing parentheses, or incorrectly structured statements. These errors are primarily related to how code is written and formatted, rather than concerns about the size or compatibility of data structures like arrays.

While mismatched array sizes may lead to logical errors or runtime exceptions in an application, they do not qualify as syntax errors. Syntax errors occur before the code is executed, whereas issues with array size typically manifest during execution when the program tries to perform operations on data that do not align with expectations.

In contrast, syntax errors can indeed affect app performance if not addressed, can stem from improper data type evaluations when operators do not align with the expected types, and can prevent proper reading of expressions, leading to a failure in parsing the code correctly.
