What issue exists if you index past the end of an array?

  1. Syntax error

  2. Run-time exception

  3. Undefined behavior

  4. Automatic resizing of the array

The correct answer is: Undefined behavior

If you index past the end of an array, you are attempting to access a memory location that does not exist. This results in undefined behavior, as the computer does not know how to handle this situation. Other options are incorrect because a syntax error would only occur if there was a mistake in the code itself, and a run-time exception would occur if there was an error during code execution. Automatic resizing of the array would only occur if the array was a data structure that supported resizing, and indexing past the end of the array does not fall under this case. Therefore, C is the correct answer as it addresses the specific issue of indexing past the end of an array.
