Can you use functions and structure to solve this. Using C++

Write a program to read 20 students name, grades, and course name from a batch file. Each student is taking 4 courses and there three exams per courses. Read information from a batch file and store then in an array ( Make sure that you create a batch file and then open it before you read from the file). Find average for each course and letter grade for each course. Find Grade Point Average (GPA) for all students. Criteria for Letter Grades: Average >= 90 90 > Average >= 80 80 > Average >= 70 70 > Average >= 60 60 > Average Write a program to read 20 students name, grades, and course name from a batch file.
