Copy the file readPeople. c. The main function should be in fine shape. You need to finish the function readPeople, and supply the freePeople function. readPeople Given a file handle and an array of null pointers: o Read the information (last name, first name, age ) for a single person Store that information in a person instance allocated from the heap. o Append that instance to the array argument o Attempt to read another person Here is a sample input file: Smith Granny 68 Tape Scott 32 Wire Barbara 45 You may assume: • Entries are complete. If there's a last name, then there's a first name and an age • Data is correct. Age will always convert to an integer. Q2 Place the readPeople function in your labsheet, with formatting. Consider Vim's :r (read) command, or use Bash redirect/append. freePeople This function simply returns the heap instances pointed to by the array to the heap. Do not assume that the array is dense. Check every position for a non-NULL pointer. Q3 Place the freePeople function in your labsheet, with formatting. Consider Vim's : r (read) command, or use Bash redirect/append.

Develop the program incrementally: a) start by reading and displaying each line of the input file to make sure you are reading the data set correctly. b) use the split string method to extract information from each line into a list. print the list to prove that this step is working correctly. d) convert the exam scores to type int and calculate the student’s average. display those items to prove this step is working correctly. e) create a tuple containing the six items for each student (name, exam scores, exam mean). display the tuples to prove this step is working correctly. (optionally, you may want to have the exam scores in a list so your tuple is (name, scores_list, f) append each tuple to a list. display the list to prove this step is working correctly. g) use the sort list method to re-order the tuples in the list. display the list to prove this step is working correctly. h) use a for statement to display the contents of the list as a table (with appropriate formatting). i) use a for statement to calculate the average of all scores on exam #1, then display the results. note that you could have calculated this average within the first loop, but we are explicitly requiring you to do this calculation by looping though your list of tuples. j) add the logic to calculate the average of all scores on exam #2, then display the results.
