5.Why Create the Array Data Structure From the previous analysis, we can understand that the essence of an array name is a pointer. Since we already have the pointer data type, why create the array data type? Isn’t that redundant? Can we program normally without creating arrays? The answer is: Yes, it is indeed possible … Read more
