c++ help

[BattleToad]

Hey guys, need a little c++ help if it wouldnt be too much trouble. This is for a programming class. Having a little trouble with the end of file loop. I wasnt allowed to use strings or arrays in this program or else it would look a lot cleaner.

The program reads data from a file, inputdata.txt and outputs to outputdata.txt. It reads a series of integers representing a series of grades. For instance, 76 67 83 49 1111111 75 85 70 90, is one final exam, 3 hourlies (lowest gets dropped), 7 homework assignments (1 is pass 0 is fail), and 4 programs. The homeworks have to be read in as char and then converted to ints to calc the homework grade, which is what that business is about.

The thing I cant figure out is how to put an end of file loop so that I can have multiple series of integers so that multiple students can be put in the inputdata file. So could anyone point me in the right direction as to how to set up an EOF loop for this?

inputdata >> finalExam; //inputing final exam grade
finalExamPercent = (finalExam * FINAL_WEIGHT) / 100; 
hourlyMin = INT_MAX;
           
inputdata >> hourlyOne;
if (hourlyOne < hourlyMin)
    hourlyMin = hourlyOne;
    inputdata >> hourlyTwo;
if (hourlyTwo < hourlyMin)
    hourlyMin = hourlyTwo;
    inputdata >> hourlyThree;
if (hourlyThree < hourlyMin)
    hourlyMin = hourlyThree;
          
hourlySum = (hourlyOne + hourlyTwo + hourlyThree) - hourlyMin; 
hourlyPercent = ((hourlySum / (NUM_HOURLIES - 1)) * HOURLY_WEIGHT) / 100;

homeworkSum = 0;
for (count = 1; count <= NUM_HOMEWORK; count++)
    {
        inputdata >> homeworkChar;
	homeworkInt = homeworkChar & ASCII_CONVERT;
	homeworkSum = homeworkSum + homeworkInt;
     }
         
if (homeworkSum > (NUM_HOMEWORK - 1))
    {
	homeworkSum = homeworkSum - 1;
    }

homeworkPercent = (float(homeworkSum) / float(NUM_HOMEWORK-1)) * HOMEWORK_WEIGHT;
	      
programSum = 0;
          
for (count = 1; count <= (NUM_PROGRAMS); count++)
    {
        inputdata >> program;
	programSum = programSum + program;
    }
          
programPercent = ((programSum / MAX_PROGRAM_GRADE) * PROGRAM_WEIGHT);
                    
grade = finalExamPercent + hourlyPercent + homeworkPercent + programPercent;
          
outputdata << grade << endl;

Sorry for the lack of comments

I'm not sure if this is what you looking for but couldn't you just wrap the whole whole section of code that gets the inputs, does the calculations, and outputs in an eof loop ie.

while (! inputdata.eof())
{
   code
}

I could kiss you. Thats all I needed to know, the book for this class is rather limited and EOF loops are covered in a single paragraph, which doesnt mention that bit of code at all. Thanks for the help.

Np lol, glad I could help. It's usually me thats asking for the help
