   cout << "\nPrime numbers between " << low << " and " << high << " are: " << endl;

   while (low < high) {

       if (low == 0 || low == 1) {

           isPrime = false;

       }

       else {

           for (i = 2; i <= low / 2; ++i) {

               if (low % i == 0) {

                   isPrime = false;
