Using your knowledge in e++. Demonstrate a project that contains a file called "Class Grades.txt", then rea student's names and Grades from the file and store them into separate arrays, and then do the following: 1. Firstly, you create a ID string array called "names" to store each student name. 2. Secondly, you create a 2D int array "grades" to store student's original quizzes Grades. the array has columns, the original 6 Quizzes Grades must be stored in the following columns : [0,1,2,3,4,5]. Store in th last column the average of the Grades. 3. Thirdly, Get the grades from the array called "grades", then calculate the average and determine the lete

OOP Lab #10
Using your knowledge in c++. Demonstrate a project that contains a file called "Class Grades.txt", then read
student's names and Grades from the file and store them into separate arrays, and then do the following:
1. Firstly, you create a ID string array called “names" to store each student name.
2. Secondly, you create a 2D int array "grades" to store student's original quizzes Grades. the array has 7
columns, the original 6 Quizzes Grades must be stored in the following columns : [0,1,2,3,4,5]. Store in the
last column the average of the Grades.
3. Thirdly, Get the grades from the array called "grades", then calculate the average and determine the letter
of that final grade.
Hint: The following functions are required:
1. "PutGrades" to read and save data into both "names" and "grades" arrays.
2. "Grades Average" to calculate each student Grade average, The grades average must be repented as
letters e.g : A>= 90 , b>= 80 .. Then find the Maximum and Minimum Grade.
Finally, we calculate average grades of the average column.
3. Use a function called show to display all of the results.
Assume there are exactly 20 students in the class.
