C++ Need help with this code. Can't use "using namespace std;"

Control break report

Objectives

• Read data from a text file
• Write data to a text file
• Correctly end a file input loop when end of file is reached
• Process control breaks correctly
• Calculate sums for grouping of input data
• Implement an algorithm
• Format output data on a report neatly
• Test and debug a program

Overview

This assignment involves the creation of a level break report. The data file provided has already been put into the proper sorted order. The format of each record is as follows:

• department: String
• employee id: String
• month: int
• day: int
• year: int
• hours: double

Requirements

Your task is to read the records in from the data file (cb1data.txt) and produce a report to a file named cbreport.txt.

Although the following technique is "brittle", you may read the data from the input file using the standard input extraction operator. For example, if you wanted to read one whole record in one statement and had the appropriate variables declared, you could write:
infile >> dept >> empID >> month >> day >> year >> hours;

A "priming read" is well-suited for this type of algorithm. A priming read makes a read from input just before a while loop starts, and then has the same read just before the end of the loop body. That type of read works very well when reading from a text file and checking for end-of-file. Instead of trying to read all of the fields from a single record though, it is better to just use the first field for the priming read, and read the remainder of the fields for that record as the first line within the loop. Example:

infile >> dept;
while (infile) {
infile >> empID >> month >> day >> year >> hours;
... other processing code ...
infile >> dept;
}

You have been given an algorithm to implement. There are some ambiguities to simulate a real life situation - but no errors that the instructor is aware of. You are required to use ostream manipulators (left, right, setw, setprecision, fixed, showpoint, etc.) to get the correct output formatting for this project.

Pseudocode

open input file for sequential access
open output (report) file
print headings to report file

totHours = empHours = deptHours = 0
prevID = prevDept = "$$$"
recno = 0

while there are still more records in the input file
get the next record from the input file
recno = recno + 1
if record's dept is different than prevDept and recno > 1
// employee level break
print employee's total hours to output file
add empHours to deptHours
empHours = 0
// department level break
print department's total hours to output file
add deptHours to totHours
deptHours = 0
otherwise if record's employee id is different than prevID and recno > 1
// employee level break
print employee's total hours to output file
add empHours to deptHours
empHours = 0
print formatted record detail to output file
add record's hours to empHours
prevID = record's employee id
prevDept = record's department

close input file

// employee level break
print employee's total hours to output file
add empHours to deptHours
empHours = 0

// department level break
print department's total hours to output file
add deptHours to totHours
deptHours = 0

print grand totals to output file
print footers to output file
close output file
end

Sample output:

Daily hours worked by Department by Employee

Dept EmpID Date Hours
