I need help understanding the concept of a program that prompts the user to input an integer and then outputs both the individual digits of the number and the sum of the digits.

I want it to output the individual digits of:

• 3456 as 3 4 5 6
• 8030 as 8 0 3 0
• 2345526 as 2 3 4 5 5 2 6
• 4000 as 4 0 0 0
• -2345 as 2 3 4 5

Thank you.
