please help with this assigment
In this assignment you are required to design and implement a mark analyzer information system. This mark analyzer system will read data of a group of students. The data includes students names, and marks of three subjects for each student. This data basically is stored in a text file created by a text editor (notepad etc.). Your system should display a simple text-based menu of options and operations to be applied to the data. Upon selection of any of these operations, the results are displayed in a proper format.
The grading scheme used in this system is:
Mark Grade
----------- --------
90 – 100 A
80 – 89 B
70 – 79 C
60 – 69 D
0 – 59 F
The Mark Analyzer System should be able to read students data from a data file (student.txt). The format of the data file is shown below.
Note: You must use exactly the same file format as given and the same filename (student.txt), though the data and the number of students can be different.
