Nothing teaches like an example, right?

Here is a complete example of a modular program using pseudocode.

The problem

Your client requests a program that will print the weekly timesheet report. The project manager (client) needs to log on to the timekeeping system every week and download the report. The report contains all the employees. The timesheet report is not filtered by the particular project. Employees charge their hours to each project. This allows the program to exclude records for other projects.

External to your program:

The project manager will log in to the timekeeping system and download a .csv file of all the hours charged by all employees for the week. The .csv will contain each employee number, name # hours, billing rate, project number for all charges for the week. The project manager will save this .csv file to a known directory.

Inputs, Processing Steps, Outputs

Requirements

You shall write a program which will prompt the project manager to enter the project number for the current project. Then open up the .csv file and loop through each line. If the project number is the one entered then add that line to the final report. You shall extract the number, name, hours, rate and calculate total hours. Write each employee line to the to a file, also .csv which will open in Excel.

Your program

Print_weekly_report
BEGIN
    declare TotalPay = 0.0
    declare employeeNumber,employeeName,hoursBilled,hourlyRate

    prompt for CurrentProjectNumber
    prompt for inputFilename
    prompt for outputFilename
    open inputFilename
    printHeader(CurrentProjectNumber)

    DO while not EOF
        if projectNumber = CurrentProjectNumber then
            read  employeeNumber, employeeName, hoursBilled, hourlyRate

            TotalPay = TotalPay + printWeeklyReport(employeeNumber,employeeName,hoursBilled,hourlyRate)
        end if

    LOOP

    printFooter(TotalPay)
    close input_filename
    close output_filename
END

printWeeklyReport(employeeNumber,employeeName,hoursBilled,hourlyRate)
    weeklyPay = calculateWeeklyPay(hoursBilled,hourlyRate)
        write to output_filename employeeNumber, employeeName, weeklyPay
        return weeklyPay

calculateWeeklyPay(hoursBilled,hourlyRate)
    return hoursBilled * hourlyRate

printHeader(CurrentProjectNumber)
    print "Weekly Report for " + CurrentProjectNumber to outputFilename

printFooter(totalPay)
    print totalPay + " charged to project" to outputFilename
