#include <stdio.h>

#include <math.h>

int main (void)

{

     char str[20];

     char key;

     int len;

     int i, j;

     //Input string

     printf ("Input String: ");

     gets (str);

     //Sorting

     len = strlen (str);

     for (i = 1; i <= len - 1; i++)

     {

          key = str[i];

          for (j = i - 1; j >= 0 && str[j] > key; j--)

               str[j + 1] = str[j];

          str[j + 1] = key;

     }

     //Print new string after sorting

     printf ("New string after sorting: %s", str);

     return 0;

};

Output

Input String: DIGITALG1

New string after sorting: 1ADGGIILT
