Explain the difference between declaring an array with values and declaring an array without values (specifying size).
Declaring with values initializes the array elements, while declaring without values only reserves memory.
Declaring with values creates a fixed-size array, while without values creates a dynamic array.
Declaring with values uses less memory.
There is no functional difference; it's just a matter of preference.
