slowly but surely

Jul 3rd, 2009

This is still the readStuData(ifstream &rss, int scores[], int id[], int &count, bool &tooMany) assignment. I've hit a small snag. This piece of the code works....kind of. When the program is run it prints out the table and stuff, however, when printing the grade it doesn't do it correctly. If I take away the for-loop code for printGrade and just leave the if statements, then hardcode 'int i = #', where # = a number from 0 - 21, it will print that one id and score repeatedly as well as the correct "grade" with it. But if left as is, it doesn't print "grade" correctly.

Not sure where the issue lies with this one.

Its not calculating the average score correctly. It should be <sum of all scores> / MAX_SIZE. To do that you need another loop before the one you already have

 Help with Code Tags

int sum = 0;
for(int i = 0; i < MAX_SIZE; i++)
   sum += scores[i];
average = sum / MAX_SIZE;
int sum = 0;
for(int i = 0; i < MAX_SIZE; i++)
   sum += scores[i];
average = sum / MAX_SIZE;
