Write a program that reads data from a file called sections.txt and outputs student section attendance scores.

The file is in the following format:

yynyyynayayynyyyayanyyyaynayyayyanayyyanyayna
ayyanyyyyayanaayyanayyyananayayaynyayayynynya
yyayaynyyayyanynnyyyayyanayaynannnyyayyayayny

Each line represents a section. A line consists of 9 weeks' worth of data.

  • Each week has 5 characters because there are 5 students. Within each week, each character represents one student.
  • a means the student was absent (+0 points)
  • n means they attended but didn't do the problems (+1 points)
  • y means they attended and did the problems (+3 points)
  • Section scores are capped at 20 points.

When reading the input file shown above your program should produce the following output:

Section 1
Student points: 20 16 17 14 11
Student grades: 100.0 80.0 85.0 70.0 55.0

Section 2
Student points: 16 19 14 14 8
Student grades: 80.0 95.0 70.0 70.0 40.0

Section 3
Student points: 16 15 16 18 14
Student grades: 80.0 75.0 80.0 90.0 70.0
Function: Write a C function as described, not a complete program.
