C for System Programming

Programming Assignment 5

Using an Array of Nested Struct(s)

DUE: See Canvas Programming Assignment 5 link.

You are to submit a single .c file to Canvas and nothing else (do not zip anything, no Eclipse projects, etc.)

You will be using an array made of nested data structures each of which in c are known as struct.

Your program will read from a single input file (hw5input.txt) and produce 2 output files (hw5Time.txt &

hw5Money.txt). You must name these files exactly this way.

The input file contains a list of items purchased by the customers of a store. Each line looks like this:

Smith 5 sweater $12.50

The line contains

- the name of the customer

- the number of items ordered

- the name of the item

- the price of one item

In the input file, customer purchases are mixed together. For example:

Smith 3 Sweater $22.50

Reich 3 Umbrella $12.50

Smith 1 Microwave $230.00

Lazlo 1 Mirror $60.00

Flintstone 5 Plate $10.00

Lazlo 1 Fridge $1200.00

Stevenson 2 Chair $350.00

Smith 10 Candle $3.50

Stevenson 1 Table $500.00

Flintstone 5 Bowl $7.00

Stevenson 2 Clock $30.00

Lazlo 3 Vase $40.00

Stevenson 1 Couch $800.00

Guidelines:

No more than 20 customers with names no longer than 29 characters.

Customers will purchase no more than 10 items.

Each customer’s order data will be stored as an array element

Each array element contains a customer struct which contains:

Customer Name

Array of items purchased (each element is an item struct)

An item purchased is a struct containing:

The name of the item (no longer than 20 characters)

How many of that item was purchased

The price of one item

Size of the items purchased array

Add more fields to either structure (customer or item) if you need to.

After storing all this data, your program must create two output files, the chronological listing and the financial

listing.

In the chronological listing (saved in file hw5time.txt), you must list every customer in the order in which the

customer first appeared in the input file. For each customer, you must list ordered items in the order in which

those items appeared in the input file. For the example shown above, the output would be (your output

should be formatted exactly as the below output):

Customer: Smith

Orders:

Sweater 3 22.50 67.50

Microwave 1 230.00 230.00

Candle 10 3.50 35.00

Total: 332.50

Customer: Reich

Orders:

Umbrella 3 12.50 37.50

Total: 37.50

Customer: Lazlo

Orders:

Mirror 1 60.00 60.00

Fridge 1 1200.00 1200.00

Vase 3 40.00 120.00

Total: 1380.00

Customer: Flintstone

Orders:

Plate 5 10.00 50.00

Bowl 5 7.00 35.00

Total: 85.00

Customer: Stevenson

Orders:

Chair 2 350.00 700.00

Table 1 500.00 500.00

Clock 2 30.00 60.00

Couch 1 800.00 800.00

Total: 2060.00

Note: Flintstone is the fourth customer because in the input file, he is the fourth customer to be mentioned. The

plate he ordered is listed before the bowl because that is the order of the items in the input file.

In the financial listing (saved in file hw5money.txt), you must list the customers in order of the total value of

their purchases, the largest total value customer appearing first. The items should be listed in order of the

value of each item, the largest value item first. (The value of an item is not the unit price, but the unit price

times the quantity ordered.) Based on the sample data given above and this criteria the output would be:

Stevenson, Total Order = $2060.00

Couch 1 $800.00, Item Value = $800.00

Chair 2 $350.00, Item Value = $700.00

Table 1 $500.00, Item Value = $500.00

Clock 2 $30.00, Item Value = $60.00

Lazlo, Total Order = $1380.00

Fridge 1 $1200.00, Item Value = $1200.00

Vase 3 $40.00, Item Value = $120.00

Mirror 1 $60.00, Item Value = $60.00

Smith, Total Order = $332.50

Microwave 1 $230.00, Item Value = $230.00

Sweater 3 $22.50, Item Value = $67.50

Candle 10 $3.50, Item Value = $35.00

Flintstone, Total Order = $85.00

Plate 5 $10.00, Item Value = $50.00

Bowl 5 $7.00, Item Value = $35.00

Reich, Total Order = $37.50

Umbrella 3 $12.50, Item Value = $37.50

You are expected to decompose your program to at least functions that perform the following tasks:

Read in the data from the input file

Generate the output file named hw5Time.txt (described above)

Sort customers’ items based on total value of the item

Sort customers based on the total value of all purchases

Generate the output file named hw5money.txt (described above)

Add other separate functions as you see fit as there are good opportunities to do so. The same rules of good

programming practices required in previous assignments apply here.

In general, you will have a list of customers and each customer will have a list of purchases. As you read

through the input file, you will often need to add another customer to your list of customers. You will also have

to add another item to some customer's list of items. At some point, you will sort all the lists.
