Question
Question 3 (10) Write a program that will calculate a student's year marks for all his subjects. The program must read the subject code, the assignment marks for two assignments and the percentage that each assignment contributes towards the year mark, for each subject that the student is registered for. Create an input file called assignments.dat that contains the following information for a specific student: cos1511 30 66 70 49 cos1512 25 76 75 67 cos1521 10 58 90 62 cos1501 50 62 50 57 INF1501 40 82 60 78 INF1511 20 24 80 55 The first field in each line represents the subject code, followed by the percentage that assignment 1 contributes towards the year mark and the student's mark (a percentage) for assignment 1. Then follow the percentage that assignment 2 contributes towards the year mark and the student's mark for assignment 2. You should not count the number of entries in the file to determine how many times the file must be read. Your program must read the file line by line, calculate the student's year mark for the subject as a perocentage and write the subject code and the year mark to an output file yearmark.dat. If your program works correctly, the output file will look as follows: cos1511 54.10% cos1512 69.25% cos1521 61.60% cos1501 59.50% INF1501 79.60% INF1511 48.80% NB: First plan your program on paper (using your computational thinking to do so). You have to submit your plan for your program as well as the actual program code, input and output. Planning your program can take the form of a flowchart, pseudocode, or notes to guide you in the development of the program.
