I've been having the most trouble working with the for loop to print out all 10 of the test scores for each of the 15 students, while also adding them up to calculate the average. Also, I'm lost with how to use the pointer. This is what continues to print out almost infinitely:

Student's ID: A0375 Student's name: Test score 1: 0Test score 2: 0Test score 3: 0Test score 4: 0Test score 5: 0Test score 6: 0Test score 7: 0Test score 8: 0Test score 9: 0Test score 10: 0's average is: 0

and ends with the same student ID..

you need to flush the input stream before getline() I think its skipping getline() which would make it print out infinitely.

inFile.ignore();
getline(inFile, name);

  • This definitely solved a lot of the problems I was facing, but now I am struggling to print out the average. I keep trying to use a pointer to display the average, I also thought I should try using a getter function to somehow make it easier... – user2495587 Apr 16 '17 at 06:59
  • What does the program print out for average? – Manvir Apr 16 '17 at 07:48
  • I've tried different ways of "outFile << name << "'s average is: " << average;" and it either doesn't run, prints 0, or prints 0x0. I'm having trouble understanding how to print it. How do I use a pointer here? – user2495587 Apr 16 '17 at 07:56
  • I think the problem is cause by the double Student::Average function. (https://stackoverflow.com/questions/3473438/return-array-in-a-function) and did you use the setAverage function? – Manvir Apr 16 '17 at 07:57
