Usage of Arrays, Functions and Files
Students are expected to write, compile, run and test a complete C program to evaluate multiple-choice examination results of the students. For that purpose, three text files are provided involving student’s information, answers, and the solution key. Solution key ‘booklet.txt’ contains three rows containing correct answers for three different booklet types, namely, A, B, and C. Student’s answers are given in ‘answers.txt’. Student’s departmental information is given in ‘students.txt’. The program shall read all three files and produce a new file called ‘results.txt’ containing the results in the given format.
‘booklet.txt’ content looks like below (each booklet type has 50 correct answers)
ACBAA*DBC*DDAACDBACCABDCABCCBDDABC*CABABABCBD*AABD
