Q1. - Find The Bugs (5 bugs)

//  College maintains a master file of students and credits earned.
// Each semester the master is updated with a transaction file
// that contains Student ID and credits earned during the semester.
// Each file is sorted in Student ID number order. Student name only exists in the master file.

Q2. - The  Library keeps a file of all books borrowed every month. Each file is in Library of Congress number order and contains additional fields for author and title. Write the pseudocode for a program that merges the files for January and February to create a new file with all of the books borrowed in the two-month period. Be sure to use appropriate modules!

Q3. - Do the following Exercise. Be sure to use appropriate modules! 

Norman's Department Store keeps a record of every sale including a transaction number (T1, T2,…), the dollar amount of the sale, and the department number in which the sale was made (department number values are 1 through 3 for this example). Design the logic for a program that inputs the sales data (transaction number, dollar amount of sale, and department number) which are sorted by department number, and outputs a report to a file showing the department number, transaction number and amount for each sale, with a total dollar amount at the change/end of each department and a Grand Total at the end of the report (see sample below).

Sample data for "NormanSales.txt" inputfile:
T1, 250, 1
T2, 500, 1
T3, 100, 2
T4, 300, 2
T5, 200, 2
T6, 350, 3
T7, 250, 3
T8, 150, 3

Sample of the OUTPUT (report file - "NormanReport.txt") - do not worry about the spacing between data:

                    Sales by Department
    Department       Transaction        Sales Value
            1                          T1                     250
            1                          T2                     500
    Department Total is 750
            2                          T3                    100
            2                          T4                    300
            2                          T5                    200
    Department Total is 600
            3                          T6                    350
            3                          T7                    250
            3                          T8                    150
    Department Total is 750
    Grand Total is    2100
