Question

can someone make unique number function, function prints all unique numbers in array?

Answer 1

We can use two nested loops. The outer loop picks an element one by one and inner loop checks if the element is present on left side of it. If present, then ignores the element, else prints the element.

C++ Implementation

#include <iostream>
#include <algorithm>

using namespace std;

void printUniqueIntegres(int arr[], int n)
{
    // Pick all elements one by one
    for (int i=0; i<n; i++)
    {
        // Check if the picked element is already printed
        int j;
        for (j=0; j<i; j++)
           if (arr[i] == arr[j])
               break;

        // If not printed earlier, then print it
        if (i == j)
          cout << arr[i] << " ";
    }
}

int main()
{
    int arr[] = {6, 10, 15, 14, 19, 1120, 14, 6, 10};
    int n = sizeof(arr)/sizeof(arr[0]);
    printUniqueIntegres(arr, n);
    return 0;
}
