In C 

Write a program that expands on the previous question (i.e. reading data of
each record in the file and storing it into your data structure). The expansion
involves writing all records to a file (use fprintf, call name the file
output.csv). The displayed data must be accessed (and thus written) from your
data structure (i.e. array of structs). The format written to the file should be
one line per record, with each field separated by a comma (‘,’).

The code for this should occur after the code for point 1f above and before
point 1g. Close both files.
Your program should then output the number of lines in the file – this code
can occur after point 1f. You should test the program by creating a text file
with at least 10 lines of text (of any composition). Use notepad++ to create the
data file.
