Answer: int[] size;
int size[];
Explanation: The declaration of the array is done with the appropriate type of datatype and associated with the length of the array in the "[]"brackets . The number input present in the "[]" defines about the length of the string that is being used in the particular program.
int[] size; and int size[]; are the correct declaration and other two options are incorrect because in []int size; length cannot be given before datatype declaration and 'int array size " does not have"[]" to mention the array length.
