Converting Digits to Words

i reading stephen g. kochan book obj-c , in end of every chapter, there few exercises train have learned far.

having little problem 1 exercise supposed write small program convert digits words. (input: 34524, output: 3 4 5 2 four) tried searching google there examples rewriting number text (1423, 1 thousand 4 hundred twenty three).

figured out how rewrite backwards (4213, 3 1 2 four), can't figure out how save digits front back.

here's backwards program:

code:

 #import <foundation/foundation.h>  int main (int argc, char *argv [])  {     @autoreleasepool {                       int number, enddigit;                  nslog(@"type number");                  scanf("%i", &number);                  (; number % 10 != 0; number /= 10){             enddigit = number % 10;             switch (enddigit){                 case (1):                     nslog(@"one");                     break;                                      case (2):                     nslog(@"two");                     break;                                      case (3):                     nslog(@"three");                     break;                                      case (4):                     nslog(@"four");                     break;                                      case (5):                     nslog(@"five");                     break;                                      case (6):                     nslog(@"six");                     break;                                      case (7):                     nslog(@"seven");                     break;                                      case (8):                     nslog(@"eight");                     break;                                      case (9):                     nslog(@"nine");                     break;                                      case (0):                     nslog(@"zero");                 break;             }             }     }          return 0;      }

i don't have particular book using, i'd guess question part of book.
if so, shouldn't try find way save words after converting them digits, rather find way convert significant digit first, , on.

code now, happens when input example 10 or 100? or number containing zero?
