A pin number is a four-digit number whose digits sum is a multiple of 10. A one check digit is usually added to the right of a three-digit number to form the pin number. For example, for the three digits number 572 we add the digit 6 to the right to form the pin number 5726 whose digits sum 5+7+2+6 is 20 which is a multiple of 10. Write a program that prompts the user to enter a three digits number then form and print the pin number. Sample input/output: Enter a three digits integer: 586 The pin number of 586 is 5861 Enter a three digits integer: 235 The pin number of 235 is 2358 C++
