ESc 014

Objectives

• Use call-by-value and call-by-reference parameters
• Practice implicit and explicit casting

Your Mission

The Input

• The first 2 lines show the name of the assessor and the township being assessed. These should be printed as the title of your report.
• Each set of 2 lines thereafter show the property owner's initials (3 characters) and the market value of his/her home.
• The last line of the file will be a 0 to be used as a sentinel.

The second file, named yourNameHere.cpp, is the starter code you should begin with. I am providing you with the main() function you need to use. YOU ARE REQUIRED TO USE THIS main FUNCTION AND YOU MAY NOT ALTER IT. In order to get this main function to work correctly, you need to write the following functions:

• The printTitle function will take the assessor's first name, last name, and the township being assessed as parameters. It will display this information as the title of your report. It will then display the column headings of the table you need to create.

• The processData function will take the input file stream variable as a parameter. This function will process the remainder of the input file by reading each property owner and market value, computing its assessed value and property taxes, and then displaying that information in your table. Process each market value as you read it. Don't use an array to store all the values first. To help processData do some of these tasks, processData will itself call a couple of other functions described below.

• The computeTaxes function will be called by the processData function. It will take a house's market value as input and give back two results: the assessed value of the property, and the tax to be collected. Be careful here. In the report you print, the assessment value will have both dollars and cents, but only whole dollars are considered when computing tax (the text says that the tax rate is 125 mils per dollar of assessed value). So cents aren't considered. However, the figure you get for the final tax should be printed as dollars and cents since the government will want to get every penny it can.

• The printOneLine function is also called by the processData function. It will print one line of the table once a home's property taxes have been computed. It will take four parameters (inputs): the owner's initials, house market value, house assessed value, and the property tax.

Hints

1. Plan your programs out first! Don't just start typing away at the computer. Figure out what the main function I gave you is doing and why it's calling certain functions in a particular order.
2. Part of this assignment is getting practice with call-by-reference vs. call-by-value parameters. Figure out where you will use each type of parameter first so you'll have a better notion of what each function's job is.
3. Don't lose points needlessly for not including everything you need to. Read the assignment and the problem in the text carefully. Don't forget to include the total taxes collected and the total number of properties at the end of your table!
4. Don't write your entire program all at once. Write each function one at a time. Compile as you go. Test each one before moving on to the next one.

Grading

• 25 pts for correct and complete output
• 10 pts for correctly implementing the required functions
• 10 pts for good documentation including output formatting
• 5 pts for good C++ language usage including casting and parameter usage

Remember to turn in both a paper and an electronic copy of your project on BlackBoard. Name your file with your FULL NAME along with the assignment number (e.g. chrisfernandes_hw4.cpp)
