Question

Lab Description: For this assignment, practice using multidimensional arrays It will read CLA4.csv. CLA4.csV contains a table of students grades for several graded items (see the following) name gradeO/grade1 grade2 grade3 grade4Igrade5 grade6 grade 7Igrade8 grade9 student0/77/90/69/89/66/62|70/80/69/86 Format The items are all separated by a “". There are 10 grade items and 10 students Read Read the first line and skip the first column (name) and store the remaining column headers (grade(Ü) in a string array called gradeltems From the second line to the end, the format is the same. Store the first column (student(i)) in a string array called students. Store the remaining columns in a multidimensional array called scores Loops Get the sum and average of the scores for each of the gradeltems and each of the students. This will require that a nested loop for the sum and average the gradeltems and another nested loop for the sum and average of the students Output The output should be stored in a file called cla4Stats.csv. It is not required to be separated by a specified format. The gradeltems statistics information should be saved in the following order: grade(i) sum average The students statistics information should be saved in the following order student i)lsum laverage
