Comparing elements in the same array

[swivel]

How do I write a function that will compare the elements in the array? Example: my array is 1, 2, 3, 4, 5.

I want to compare if

1 = 2
1 = 3
1 = 4
1 = 5
2 = 3
2 = 4

I tried using a for loop and nested for loop and I still can't seem to get it correct. Any help will be great;

Hope this helps

#include <iostream>

using namespace std;


int main()
{
    int arr[5] = {1,2,3,4,5};
    
    for(int i = 0; i < 5; i++)
    {
        for (int j = 1; j < 5; j++) {
            cout << arr[i] << " "<< arr[j] << endl;
        }
    }
    
    return 0;
}

Your question is so vague. Why would you compare if 1 = 2?
