CSE 142 Homework 2

Due Sunday, July 9th, 10:00 PM
Paper turn in Monday, July 10th, 5:00 PM

Overview

As the head software engineer at HHGG, you will write a program to help order the supplies needed to keep your team strong and alert. You will use what you learned on your last project, as well as your new knowledge of conditionals and functions. Read the entire assignment carefully and thoroughly. Pay close attention to the specifications below, as that details what your program must do.

Quick Overview

• Read the Specifications
• Look at the Sample Program Runs
• Download the Sample Executable
• Download the starter code:
  • Those using MSVC 6 (in MGH, OUGL, or at home) should get the MSVC 6 self-extracting archive
  • Those using MSVC 5 need the MSVC 5 self-extracting archive
  • All other users need the plain source file hw2.c. Help setting up projects for some other environments can be found on the homework help page.
• Write the program
• Turn in the program

Specifications

This is a simple program to create order forms based on a request for a few (6) greatly needed items from 3 different suppliers. You can order Coke, Beer, Sugar Stix, Caffeine, Burgers, and cheese Pizza. These items have the following costs:

As this program is fairly complex, you may want to first look at the Sample Executions.
Also, you will find the starter code very helpful for this assignment.

• The number of cans of Coke desired
• The number of bottles of Beer desired
• The number of Sugar Stix desired
• The number of grams of Caffeine desired
• The number of Burgers desired
• The number of Pizzas desired

Based on the values input above, it will generate order requests to the suppliers:

Your program should generate the following output:

• If at least one (1) item is ordered from a supplier, then an order request should be generated for that supplier.
• Only one (1) order request per supplier
• No order request if neither of the suppliers' items were desired
• An order request should contain the following:
• The name of the supplier of the item(s)
• The quantity, name, and cost of purchasing that many of the first item (if the quantity is greater than zero)
• The quantity, name, and cost of purchasing that many of the second item (if the quantity is greater than zero)
• The sub-total of this order
• Lastly, you should print the total cost of all orders

1. MakeOrder -- This function takes a supplier number (listed above), an item number, the quantity for that item, and a second item number and quantity. It will produce the order request for the intended supplier and items (as specified above). It returns the cost of the order. It will make use of the following functions:
2. printSupplierName -- This function takes a supplier number (see above) and prints the name of the supplier corresponding to that supplier number.
3. printItemName -- This function takes an item number (see above) and prints out the name of the item corresponding to that item number
4. PerItemCost -- This function takes an item number and returns the cost of a single unit of that item (see above).

See the following page for sample executions.

Suggestions and Hints

You should make good use of constants, conditionals, comments, and the switch statement. Don't forget the return statement in functions that return values.

Remember, it is better to have a program that compiles and runs without complete functionality, than a program that doesn't compile or run. Consider writing the program in smaller pieces, and testing those. For example, write the input, test, a function, test, etc.

Sample Executable

Download and run the sample PC executable hw2.exe.

See some sample runs of the program.

Getting Started

We've provided a workspace and starter code to help you on your way, including function definitions.

Submitting Your Work

Use the turnin page.

You may turn in the program as many times as you wish. Only the last version is graded, and only the receipt from this last version should be handed in.
