Question

The program is to print the student scores and calculate and print the statistics for each quiz. The output is in the same order as the input; no sorting is needed. The input is to be read from a text file. The output from the program should be similar to the following:

In this assignment create and implement an interface to:

Print student statistics.

Print scores for a given student id.

implement the Debug flag globally

Think of possible opportunities for using an Abstract class. Create and implement an abstract class in the assignment.

Here is a copy of actual data to be used for input.

Stud Qu1 Qu2 Qu3 Qu4 Qu5

1234 052 007 100 078 034

2134 090 036 090 077 030
