In a C programming language

Your task is to code in a C programming language to read in student names and grades from separate files, and write a third file containing a summary of student grades as output of your programme. Below will also be a screenshot of all the data you will need, you can create your own csv file with the data I am going to provide in the screenshot

Details

Your program should read in a student or results CSV file, an activity CSV file, and output a third results CSV file containing a summary of the grades for each student. Your program should take three command line arguments: the filename of the student CSV file or a previously generated results CSV file, the filename of the activity CSV file, and the filename of the results CSV to write to respectively.

The first line of results CSV file should contain a header with the following format:

id,last_name,first_name,average,grade01,grade02,...

And then a line for each student (in the same order as they appear in the student CSV file) giving their ID, last name, first name, arithmetic mean of activity grades (to two decimal places), and the grades for each activity.

If your program is run with a student CSV file as its first argument, the results CSV file will just contain the following columns:

id,last_name,first_name,average,grade01

If your program is run with a results CSV file as its first argument, an extra column should be created listing the grades in the activity CSV file, and the average column updated to reflect the average grade across all previously recorded activities.

For example, if the following command is run:

$ ./task3 class01_students.csv class01_activity01.csv class01_results01.csv

The contents of theclass01_results01.csv file will be:

id,last_name,first_name,average,grade01

3444670,Hurrington,Sherri,30.00,30

3611390,Rich,William,0.00,0

2939734,Simmons,Erin,16.00,16

288301,Levi,Antonio,75.00,75

1295620,Henderson,Mabel,41.00,41

2890792,Osterberg,Marty,0.00,0

1274266,Winders,Nancy,90.00,90

Then, if the following command is run:

$ ./task3 class01_results01.csv class01_activity02.csv class01_results02.csv

The contents of theclass01_results02.csv file will be:

id,last_name,first_name,average,grade01,grade02

3444670,Hurrington,Sherri,37.00,30,44

3611390,Rich,William,0.00,0,0

2939734,Simmons,Erin,45.50,16,75

288301,Levi,Antonio,86.00,75,97

1295620,Henderson,Mabel,35.00,41,29

757790,Coffey,Paula,75.50,62,89

3149175,Green,Tom,59.00,56,62

3173019,Willis,Hazel,80.00,70,90

2890792,Osterberg,Marty,6.50,0,13

You are free to choose whichever method you want to implement your program with the following restrictions:

• your implementation must contain a correctly declaredmain function
• you are not allowed to use global variables
• all dynamically allocated memory should be freed
• all user file handles should be closed

You can use any standard library functions (including those in the C maths library).

Your program will be tested against a number of randomly generated classes Your program will also be tested against a number of invalid cases e.g. an incorrect number of command line arguments, or incorrect numbers of columns in the student or activity CSV files. In these cases, an error message should be printed and your program should immediately exit with a non-zero exit code. All error messages in your implementation should be printed tostderr.

Your program should handle dynamically allocated memory correctly i.e. free all dynamically allocated memory. It should also make sure all user file handles are closed before it exits.
