Looping through a text file and outputting different data In C++ - c++

Question

My code asks me to convert:
2 6 2 // # of quizzes (2), homeworks(6), exams(2)
Solution Key 10 10 10 10 20 20 20 20 100 100
Washington George 10 10 10 10 20 20 20 20 100 100
Jefferson Thomas 10 0 8 6 20 15 13 0 80 90
Franklin Benjamin 0 0 0 0 20 10 20 10 100 50
Lincoln Abraham 10 5 10 5 0 0 0 0 80 30
Madisonville James 5 7 9 3 10 12 14 16 0 0
Wilson Woodrow 2 4 6 8 10 12 14 16 74 89
Hoover Herbert 0 10 10 10 0 20 20 20 0 100
Roosevelt Franklin 0 0 0 0 0 0 0 0 0 0
Into this (in an output file):
# Last First Quiz HW Exam Total Average
- ---------- ----- ---- --- ---- ----- -------
Solution Key 20 100 200 320 100.00
- ---------- ----- ---- --- ---- ----- -------
1 Washington Georg 20 100 200 320 100.00
2 Jefferson Thoma 10 62 170 242 75.62
3 Franklin Benja 0 60 150 210 65.62
4 Lincoln Abrah 15 15 110 140 43.75
5 Madisonvil James 12 64 0 76 23.75
6 Wilson Woodr 6 66 163 235 73.44
7 Hoover Herbe 10 80 100 190 59.38
8 Roosevelt Frank 0 0 0 0 0.00
- ---------- ----- ---- --- ---- ----- -------
Class Average = 55.20
I have been using count controlled loops to obtain the quiz, homeworks, and exam scores, however my output looks like this:
# Last First Quiz HW Exam Total Average
- ---------- ----- ---- --- ---- ----- -------
- ---------- ----- ---- --- ---- ----- -------
- ---------- ----- ---- --- ---- ----- -------
Class Average = 1458176112

TLDR: How do I loop through a text file and get its info, use them in calculations, and output it correctly?
