Find the 3 repeating numbers within an array

C++

Hi all, I am trying to write a function of 5 dice rolls where it should count the number of times whether 3 same numbers appear eg. (5,5,3,1,5)

Before that, I already have a function for pairs which works. But the following function which I wrote for threeSameNo, it seems to work for pairs too (4,2,4,1,2) or sometimes, it does works where there is indeed 3 same numbers, and times it did not work when re-running the program even if there are 3 same numbers.

Am I doing wrong somewhere?

FYI, getValue is a function I wrote for getting the value of each dice that is stores within an array.

What I have tried:

void DiceRoll::threeSameNo()
{
    int counter = 0;

    for(int i = 0 ; i < 5 ; i++)
    {
        for(int j = i + 1 ; j < 5 ; j++)
        {
            for(int k = j + 1 ; k < 5 ; k++)
            {
                if (dArray[i].getValue() == dArray[j].getValue() == dArray[k].getValue())
                {
                    counter++;    
                    cout << "Three of A Kind appear " << endl;                
                }
            }
        }
    }
    
}
