Each student listed in the file roster.txt will have their own data file. The file will be named FDDDDDDDDDDL.data, where F is the student's first initial, in upper case, L is the student's last initial, also uppercase, and DDDDDDDDDD is the student's id number. So the previous roster.txt file would have associated files named:

B1234567890J.data
T1111111111J.data
W0987654321S.data
W9999999999S.data
A1010101010S.data

• Three integers, between 0 and 100, representing the student's homework scores.
• Two integers, between 0 and 100 representing the student's program scores.
• Two floating point numbers, between 0 and 1 representing the student's test scores.

90 80 87 100 99 .86 .79

Each student should have an individual report file in the following format:

• The first line should contain
  • First Name
  • A space
  • Last Name
• The second line should contain the students id number.
• The third line should contain
  • The word "Homework:"
  • A space
  • The student's three homework scores separated by a space.
  • The student's homework average, as a percentage, To one decimal place.
• The fourth line should contain
