Array size

We can generally use sizeof (array name)/sizeof (array Element) to find the number of array elements, but it should be noted that when we need to call the function to handle the array, the length of the array is to be obtained before calling the function, because when the function is called, The array is degraded to a pointer (only the first address of the array is passed into the parameter), and in a 32-bit system, any type of pointer is 4 bytes.
