- Question 1. Suppose that the grading of x University courses is as follows: • Each student can get grades between 0 and 100. • If the grade of the student is less than 40, the student is informed that he failed the course ( Failed ). • If the student's grade is higher than 40 , o The difference between the student's current grade and the number that is a multiple of the 5 higher than the closest to his / her grade is less than 3. If it is lower, the student's grade is equal to the 5 times higher than the closest one. o If the difference is 3 or more than 3 , no change is made in the grade of the student . In this context, the updated grades of the students are calculated according to the entered student grades and printed on the screen. Write the Java code showing.and c++code showing. V Define the section to be calculated as Java object (" Question1 ").
