int CalculateSum (int AnalyticalScore, int QuantitativeScore);
int PrintReport (int StudentID, int AnalyticalScore, int QuantitativeScore, int SumOfScores);


main ()
{
  int StudentID=999;
  int AnalyticalScore=999;
  int QuantitativeScore=999;
  int SumOfScores=999;
  int iNum=0;
  int i;
   for(i=1;i<=iNum;i++)
  {
    int ReadData(int iNum)
    {
      printf("Please enter the number of students: ");
      scanf("%d", &iNum);
    }

    int CalculateSum(int AnalyticalScore, int QuantitativeScore)
   {
     SumOfScores=AnalyticalScore+QuantitativeScore;
   }

   int PrintReport(int StudentID, int AnalyticalScore, int QuantitativeScore, int SumOfScores)
  {
     printf("Student ID: ", &StudentID);
     printf("Analytical Score: ", &AnalyticalScore);
     printf("Quantitative Score: ", &QuantitativeScore);
     printf("Sum of Scores: ", &SumOfScores);
  }
 }
