Write a c program which deletes the duplicate element of an array.?

 #include<stdio.h>  
  #include<conio.h>  
  int main()  
  {  
   int arr[20], i, j, k, s;  
   printf("\nEnter array size : ");  
   scanf("%d", &s);  
   printf("\nAccept Numbers : ");  
   for (i = 0; i < s; i++)  
    scanf("%d", &arr[i]);  
   printf("\nArray with Unique list : ");  
   for (i = 0; i < s; i++)  
  {  
    for (j = i + 1; j < s;)  
  {  
      if (arr[j] == arr[i])  
 {  
       for (k = j; k < s; k++)  
 {  
         arr[k] = arr[k + 1];  
       }  
       s--;  
      }  
  else  
       j++;  
    }  
   }  
   for (i = 0; i < s; i++)  
 {  
    printf("%d ", arr[i]);  
   }  
   return (0);  
 }  
 Enter array size: 5  
 Accept Numbers : 1 3 4 5 3  
 Array with Unique list : 1 3 4 5
