On a given exam, the points awarded for each problem are recorded in a text file, with one line of the file for each student that took the exam. Create a program that reads this text file and determines
each student’s total grade for the exam
the class average for the exam
the average number of points given for each problem
The input data file will be a plain text file with each number separated by a single space.
All numerical data (student ID, scores) must be stored in a 2-dimensional array.
The final column of the array should hold the total score for each student. Caution: do not include the student ID in the sums!
The final should hold the averages for each column.
There will be 4 problems and 5 students, so the array should hold 6 rows (5 students + average) and 6 columns (ID, 4 grades, and exam total).
All calculations and array access must be performed using pointers and dereferencing. You may use [ ] only when reading and writing the data files.
The results must be printed to the screen as well as written to a file in table format.
Your program should contain the following functions: main, loadDataFile, calculateResults, writeResultsFile, and printResults.
main – create empty 6x6 2-D array to hold data and then call other functions as needed, passing them the array
loadDataFile – read the input file, storing the data in the 2-D array
calculateResults – performs all calculations
writeResultsFile – creates and writes the resulting array to the output data file
