Average of a quiz

The problem involves reading the attached csv file which contains quiz data for 28 students. The data is to be read into a two dimensional array of int. Since each row will be read in as a string with comma delimiter between each grade it is recommended (but not required) that you use the c++ string tokenizer to extract each grade from each row. After extracted, it will still be a string so it must be converted to an int. Use the appropriate built in c++ function to accomplish this conversion. After filling the array your mission will be to compute each of the 28 student's average by dropping the two lowest grades in each row and finding the average of the remaining three grades. These 28 averages are to be stored in a one dimensional array called average. Also, each column of data in your two dimensional array contains all the quiz scores for any given quiz. For example, the first column contains the data for quiz 1 and the 5th column contains the data for quiz 5. You are to compute the grand average quiz score for each and store this data in another one dimensional array called quizAvg. Finally, you are to compute the average of both the average array and the quizAvg array. Your output will be to the console and will contain all the data in the average array, the quizAvg array and the grand averages.
