I have this bubble sort I need to add a counter to check the

I have this bubble sort. I need to add a counter to check the comparisons. In order words, how often I check one element in the array against another.
Am I doing it, right? If not, How can I fix it? Thank you

#include <iostream>
using namespace std;

void bubbleSort(int theArray[], int n)
{
   int comparisons = 0; //counter is
   bool sorted = false;
   int pass = 1;
   while(!sorted && (pass<n))
   {
       // At this point, theArray[n+1-pass .. n-1] is sorted
       // and all of its entries are > the entries in theAraay[0..n-pass]
       sorted = true;
       for(int index = 0; index < n-pass; index++)
       {
           comparisons++;
           // At this point, all entires in theArrat[0.. index-1]
           // are <= theArray[index]
           int nextIndex = index+1;
           if(theArray[index] > theArray[nextIndex])
           {
               //exchange entries
               swap(theArray[index], theArray[nextIndex]);
               sorted = false; //signel exchange
              
           } // end if
       } //end for
       //asseertion: theArray[0..n-pass-1] < theArray[n-pass]

       pass++;
   }//end while

   cout << \"Number of comparison: \" << comparions;
}//end bubbleSort;

void displayArray(int theArray[], int size)
{
   for(int i=0; i <size; i++ )
   {
       cout<<theArray[i]<<\" \";
   }//end for
}// end displayArray

int main()
{
   int data[] = {1};
   //int data1[] = {2, 1};
   //int data2[] ={ 1,2};
   int data3[] = {4, 1, 3, 2, 0, 7};

   cout<<\"The array data contains: \" << endl;
   displayArray(data,1);
   cout<<endl;
   bubbleSort(data, 1); // the int is the size of the
   cout<<endl;
   cout<< \"The array data after sorting: \" << endl;
   displayArray(data,1);
   cout<<endl<<endl;

   cout<<\"The array data3 contains: \" << endl;
   displayArray(data3,6);
   cout<<endl;
   bubbleSort(data3, 6); // the int is the size of the
   cout<<endl;
   cout<< \"The array data3 after sorting: \" << endl;
   displayArray(data3,6);
   cout<<endl;

   int array8a[] = {1, 4, 23, 37, 2, 7,3, 9};
   int array8b[] = {9,7,2, 37, 23, 4, 1, 3};

}

Solution

The program is perfect to check the number of comparisons occured during bubble sort.

however you have made a mistake in: cout << \"Number of comparison: \" << comparions;

it should be comparisons. Rest assured i could not find any problems with the code or the way to calculate the comparisons done.

please comment for any other clarifications as i believe the question is answered.
