Quiz Practice:
int a[] = {1,2,3,} *p;
E. None of the above
Correct Answer: None of the above.
The given statement is not a complete executable program. It contains an array declaration and a pointer declaration, but the pointer p is not initialized to any valid memory address and no operation is performed that would produce an output.
The array contains the values 1, 2 and 3, but this does not mean that the output will automatically be 3. Similarly, an uninitialized pointer does not automatically produce a specific runtime error in this incomplete statement.
Therefore, among the given choices, None of the above is the appropriate answer.
Exam point: An array declaration and a pointer declaration alone do not produce output. A pointer must be assigned a valid address before it is safely dereferenced.
