C++ program to print all distinct elements in a given array

#include <iostream>
#include <algorithm>
using namespace std;

void printDistinct(int arr[], int n)
{
    // First sort the array so that all occurrences become consecutive
    sort(arr, arr + n);
    int i=0;

    // Traverse the sorted array
    while(i<n)
    {
    if(arr[i]==arr[i+1])
    {
    i=i+1;
    }
    else
    {
    cout<<arr[i]<<endl;
    i++;
    }
    }
}

// Driver program to test above function
int main()
{
    int arr[] = {6, 10, 5, 4, 9, 120, 4, 6, 10};
    int n = sizeof(arr)/sizeof(arr[0]);
    printDistinct(arr, n);
    return 0;
}
