Write programming code in C++ for school-based grading system. The program should accept the Subject and the number of students from a user and store their details in an array of type Student (class). The student class should have: • studName, indexNo, remarks as variables of type string, marks as integer, and grade as char. • A void function called getData which is used to get students’ details (index number, name, and marks). • A void function called calculate which will work on the marks entered for a student and give the corresponding grade and remarks as give below. Marks Grade Remarks 70 – 100 A Excellent 60 – 69 B Very Good 50 – 59 C Pass 0 – 49 F Fail • Should be able to display the results for all students (index number, name, marks, grade, remarks). 2. Draw a flowchart for the calculate function above. 3. Create a folder with name format ICTJ254_indexnumber (eg
