C++, sorting an array and dumping duplicate values

I have an array that was bubble sorted alphabetically.  Now I have the array but have duplicate values.  I want to print out the array but not print the duplicate values.  We are about 4 weeks into the course so I'm hoping the solution is not too complex

Heres a pseudo code..assuming the array is sorted.


   i = 0
   j = i + 1

 For loop = 0 to ARRAY_SIZE {
    If (arr(j) != arr(i)){
      Print arr(i)
      i = j        
    }
     j++      
  }
 
int nArraySize = 250;

int* pArray = new int[nArraySize]; //the array with some values

// your sorting goes here

int nOldValue;
int nNewValue;

for( int i=0 ; i<nArraySize ; i++ )
{
   nNewValue = pArray[i];
   bool bWrite = (i==0); //first value is always written

   if( bWrite==false ) //if not the first, check if new value is the same
   {
      bWrite = (nNewValue!=nOldValue);
   }

   if( bWrite )
   {
      cout << nNewValue << endl;
   }

   nOldValue = nNewValue; //remember last value written
}
