MY PROGRAM IS NOT RUNNING..NEED HELP ON THIS..
At the beginning of the system, you need to input number of students and number of subjects that have been marked. Then, you need to enter the student's identification number and marks for each subject. While entering the marks, you have to determine their respective grades and display the grades based on the following table:
80 ≤ marks ≤ 100 A
70 ≤ marks ≤ 79 B
60 ≤ marks ≤ 69 C
50 ≤ marks ≤ 59 D
40 ≤ marks ≤ 49 E
marks ≤ 39 F
After determine the grades, you need to come out with the total marks and find the average marks of the subjects. If the average marks is greater than or equal to 40, the respective student can proceed to the next semester.
