Thread: getting garbage values in the ouput i guess code is correct !!!

Write a C function with 1-D array and its size as arguments, which is called by main() function and remove the duplicate elements from an array also display the resultant array? ( this is the question )

Code:

#include <stdio.h>

#define MAX_SIZE 100 
int duplicate_elements(int arr[], int n);
int main()
{
    int arr[MAX_SIZE]; 
    int n;          
    int i, j, k;     
    printf("Enter size of the array : ");
    scanf("%d", &n);
    printf("Enter elements for the array : ");
    for(i=0; i<n; i++)
    {
        scanf("%d", &arr[i]);
    }
   duplicate_elements(arr,n);
    printf("\nArray elements after deleting duplicates is  : ");
    for(i=0; i<n; i++)
    {
    printf("%d\t", arr[i]);
    }

    return 0;
}
int duplicate_elements(int arr[], int n)
{
	int i,k,j;
  for(i=0; i<n; i++)
    {
        for(j=i+1; j<n; j++)
        {
            if(arr[i] == arr[j])
            {
                for(k=j; k<n; k++)
                {
                    arr[k] = arr[k + 1];
                }
                n--;

               
                j--;
            }
        }
    
	}

	}
