Question
Write a C program that reads the exam data for each student from a file named grades.txt.
Each line in the file grades.txt contains
name surname midterm1 midterm2 final
for each student.
The program then calculates the weighted average according to the formula
average=0.25*midterm1 + 0.25*midterm2 + 0.5*final
and assigns a letter grade AA, BA, BB, etc , using the standard scale
average >= 90 AA
85 <= average < 90 BA
80 <= average < 85 BB
....
....
60 <= average < 65 DD
50 <= average < 60 FD
average < 50 FF
The program then writes to new fıle named grades.out
name surname midterm1 midterm2 final average lettergrade
on a line for each student.
EXAMPLE:
Suppose the file grades.txt contains the lines:
ali veli 45 50 70
ahmet mehmet 60 70 80
ayse fatma 66 77 90
Then the outpout file grades.txt would be
ali veli 45 50 70 58.75 FD
ahmet mehmet 60 70 80 72.5 CC
ayse fatma 66 77 90 80.75 BB
