7. Write a program to define an integer array and integer array
list. Show the difference in creation, addition and modification
of elements.
8. Write a program that prompts the user to input a positive

9. Write a program to print out all Armstrong numbers between
1 and 500. If sum of cubes of each digit of the number is equal
to the number itself, then the number is called an Armstrong
number.
For example, 153 = ( 1 * 1 * 1 ) +( 5 * 5 * 5 ) + ( 3 * 3 * 3 )](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F722c0934-aff7-4600-989e-1d198e6697ab%2F5ac0f9cd-d47f-4e2b-aa2f-e3c079322b67%2Fsew4etl_processed.jpeg&w=3840&q=75)
