#include<stdio.h> #include<math.h>   int main()   {       Int  a, n, r, k, temp;       printf( "Enter an integer number: " );       scanf( "%d" ,&n);       temp=n;       r=0;       while(n>0)           {              r=r*10 + n%10;              n=n/10;            }         while(temp>0)            {               a=r%10;               r=r/10;              temp=temp/10;               switch (a)                 {                     case 1:                           printf( "One " );                           break;                     case 2:                            printf( "Tow " );                            break;                     case 3:                           printf( "Three " );                           break;                     case 4:                            printf( "Four " );                            break;                     case 5:                           printf( "Five " );                           break;                     case 6:                            printf( "Six " );                            break;                     case 7:                           printf( "Seven " );                           break;                     case 8:                            printf( "Eight " );                            break;                     case 9:                           printf( "Nine " );                           break;                     default :                           printf( "Zero " );                   }            }       return 0;   }
