Develop a Farmer's Market Inventory Program (CS 101, Assignment 6-A)

This assignment involves creating a C++ program to process data from a Farmer's Market inventory file (ASSGN6-A.txt). The program reads farm names, item counts, item names, and prices. It calculates the total value for each item by multiplying the count by the price. The program then generates a formatted report displaying each farm's inventory, including the calculated totals. The program also creates a new output file containing the original data with the calculated totals appended. The solution emphasizes the use of functions, file handling, and formatted output, adhering to specified requirements for headings, alignment, and data formatting. The program reads data, performs calculations, and generates a report. The report will show every item in the file and write the processed data to a new output file. The code adheres to good documentation standards and incorporates best practices for file processing and output formatting.

Assignment 6-A: Farmer’s Market I
Overview
The purpose of this assignment is to make sure that you know how to write a program that
uses files and file processing. The program also contains functions and does input, output,
flow of control and/or calculations.
PROGRAM SPECIFICATION
For the assignment, we will write a program that reads a file of information pertaining to a
Farmer’s Market. The file contains the names of various farms participating in a Farmer’s
Market. The program should create a file object for input, read the data, perform some
calculations, create a report, and then rewrite the information to a new output file.
The format of the file is as follows:
Field or data item in the file Data type Notes
Farm name String of characters This could end with a comma
Count of item Integer Number of items
Item String Name of the item
Item price Float or double Unit cost of each item
Download the file (called ASSGN6-A.txt) to examine the contents. You should see that the
name of the farm is delimited with a comma, and everything else is delimited with a space.
When reading the information into your program, the comma after farm name and the space
between each remaining field is consistent and guaranteed. Item is also guaranteed to be
one word (so probably don’t need a getline). Also, we will not need to validate the
information in this program. Valid data is also guaranteed! Your program will read the data
items and output them to a report. The count of items should be multiplied by the item
price, and that should be shown as well. The format should appear on the screen as follows:
==============================================================
= FARMER’S MARKET INVENTORY =
==============================================================
Collins Farm: 43900 tomatoes @ .67 each totaling $29413.00
…
Rutherford Farms, Inc.: 809 apples @ .90 each totaling $728.10
…
Grand total: 999999 items totaling $999999.99

Hint: Use setw() in conjunction with setfill(‘=’) for your headings. Use setw() to align your
output for the farm name. The maximum farm name is 25 characters in length. The
remainder of the line will be formatted as seen.
Read each item and output them to the console as you process the file. Your report will show
every item in the file.
As you process this file, you will ALSO be creating an output file. Your program should open
an output file object using the name of your choice for the text file, and name of your choice
for the name in your program. Rewrite each line of the input file to the output file, adding a
variable with the amount that you calculated from count of items multiplied by the item
price. Make sure that you put a space before the new total. As an example, the first item
should look like this in your file:
Collins Farm 43900 tomatoes .67 29413.00
- or –
Collins Farm 43900 tomatoes 0.67 29413.00
Do both the report and new file creation in the same loop. Otherwise, your program will be
very inefficient. Make sure you break your code into functions. Open your files in main and
pass them by reference.
Make sure that your programs follow good documentation standards and follow the
requirements for assignments. Reference the rubric standards on Springboard. Note
functions and data validation are now required. Do not use using namespace std;.
Submission Instructions – for programming solutions
On Springboard, go to the matching Assignments for the ASSGN@-#, where @ is the
chapter and # is the number or character of the problem assigned (eg., 5-11 for chapter 5,
problem 11), and submit the program (cpp) and any (hpp) files.
