Unique Number Identifying
I'm trying to solve the below problem for a number:

Enter a number and if it has all unique digits print unique number else non-unique number.
Eg:
Code:
Input=123; Output=unique number
Input=112; Output=Non-unique number

The thing i tried is splitting the number into digits by using % operator and storing it in a array and i'm facing problems while using 2 for loops to traverse the array elements and compared with each other.

Code:
for ( i=0; i<=array_length; i++){
 for( j=i+1; j<=array_length; j++){
  if ( a[i] == a[j] ){
   printf("unique");
  }
 else{
   printf("Non-unique");
  }

I know that i'm wrong, can someone help with any idea to solve.

__________________________________________________________________________________________________________________________________________________

NAME

       Tk_GetUid, Tk_Uid - convert from string to unique identifier

SYNOPSIS

       #include <tk.h>

       Tk_Uid
       Tk_GetUid(string)

ARGUMENTS

       char	    *string	       (in)	 String for which the corresponding unique identifier is desired.
_________________________________________________________________

DESCRIPTION

       Tk_GetUid  returns  the	unique identifier corresponding to string.  Unique identifiers are similar to atoms in Lisp, and are used in Tk to
       speed up comparisons and searches.  A unique identifier (type Tk_Uid) is a string pointer and may be used anywhere that a variable of  type
       ``char  *''  could  be used.  However, there is guaranteed to be exactly one unique identifier for any given string value.  If Tk_GetUid is
       called twice, once with string a and once with string b, and if a and b have the same string value (strcmp(a, b) == 0), then Tk_GetUid will
       return  exactly	the  same Tk_Uid value for each call (Tk_GetUid(a) == Tk_GetUid(b)).  This means that variables of type Tk_Uid may be com-
       pared directly (x == y) without having to call strcmp.  In addition, the return value from Tk_GetUid will have the same string value as its
       argument (strcmp(Tk_GetUid(a), a) == 0).

KEYWORDS

       atom, unique identifier
