2.28 C++ How to Program (8th Edition) By Paul Deitel, Harvey Deitel

(Digits of an Integer) Write a program that inputs a five-digit integer, separates the integer into its digits and prints them separated by three spaces each. [Hint: Use the integer division and modulus operators.] For example, if the user types in 42339, the program should print:
4 2 3 3 9 

Solution: 

 
#include <iostream>
using std::cin;
using std::cout;
using std::endl;
 
int main()
{
   int fivedigit;
   int first, second, third, fourth, fifth;
 
    cout << "Please enter the five digit integer: ";
  cin >> fivedigit;
 
    if(fivedigit < 10000)
    {
    cout << "Incorrect digit! Try again!";
  }
 
  if(fivedigit > 99999)
  {
    cout << "Incorrect digit! Try again!";
  }
 
  first = fivedigit/10000;
  second = (fivedigit/1000)%10;
  third = (fivedigit/100)%10;
  fourth = (fivedigit/10)%10;
  fifth = fivedigit%10;
 
  cout << first;
  cout << " " << second;
  cout << " " << third;
   cout << " " << fourth;
   cout << " " << fifth;
 
   return 0;
}
