Getting Started
Start by downloading CS101_Assign05_Fa24.zip, saving it in the directory H:\CS101. In Windows File Explorer, navigate to H:\CS101, right click on CS101_Assign05_Fa24.zip, and select Extract All to create a CS101_Assign05_Fa24 directory with the assignment files.
Start a Cygwin Bash Shell and run the following commands:
cd h:
cd CS101
cd CS101_Assign05_Fa24
Using Notepad++, open the files
H:\CS101\CS101_Assign05_Fa24\TaxTime.cpp H:\CS101\CS101_Assign05_Fa24\HitBox.cpp
You will add your code to these files (separately).
Your Tasks
Tax Time
Add code to TaxTime.cpp
Initially, declare a struct named Person that contains the following fields:
- social security number (int)
- filing status (int)
- gross income (double)
- deduction amount (double)
Then, the program should prompt the user to enter values for each field and store them in a struct variable. (Note: filing status is given by 1 - Single, 2 - Married joint, 3- Head of household, 4 - Married separate. Also, a negative value for the deduction amount indicates the person is taking the standard deduction).
Once the information is collected, the struct should be passed to a function named calcTaxes() which takes a single Person struct parameter and returns a double for the tax obligation. Note: The function should print out the taxable income and tax rate (for debugging), while the main program should print the final tax obligation.
Tax Obligation
The tax obligation is computed by first determining the deduction amount which is either the actual amount or the amount given by the following table based on the filing status, whichever is greater:
| Filing Status | Standard Deduction |
|---|---|
| Single | $12,000 |
| Married joint | $24,000 |
| Head of Household | $18,000 |
| Married Separate | $12,000 |
Taxable Income
The individual’s gross income is then given as their gross income minus their deduction amount.
Tax Rate
Using the taxable income, the tax rate is then determined by the following table:
| Tax Rate | Single | Married joint | Head of Household | Married Separate |
|---|---|---|---|---|
| 10% | <$10,001 | <$20,001 | <$13,001 | <$9,501 |
| 20% | $10,001-$80,000 | $20,001-$165,000 | $13,001-$82,500 | $9,501-$82,500 |
| 30% | $80,001-$200,000 | $165,001-$400,000 | $82,501-$200,000 | $82,501-$200,000 |
| 35% | >$200,001 | >$400,001 | >$200,001 | >$200,001 |
Tax Obligation
Finally, the tax obligation is given by the taxable income times the tax rate. Note: The tax obligation cannot be negative, thus if the deductions exceed the gross income, the tax obligation is $0.
When you are ready to compile the program, in the Cygwin window type the command
make TaxTime
To run the program, type the command
./TaxTime.exe
Here are some example runs (user input in bold):
Please enter SSN: 123456789 Filing Status (1-Single, 2-Married Joint, 3-Head of Household, 4-Married Separate): 1 Gross Income: 78654.00 Deductions (-1 if none): 6250.00 Taxable income: $66654.00 Tax rate: 20% Tax obligation: $13330.80
Please enter SSN: 123456789 Filing Status (1-Single, 2-Married Joint, 3-Head of Household, 4-Married Separate): 3 Gross Income: 167430.25 Deductions (-1 if none): 23410.00 Taxable income: $144020.25 Tax rate: 30% Tax obligation: $43206.07
Please enter SSN: 123456789 Filing Status (1-Single, 2-Married Joint, 3-Head of Household, 4-Married Separate): 4 Gross Income: 435890.00 Deductions (-1 if none): -1 Taxable income: $423890.00 Tax rate: 35% Tax obligation: $148361.50
Please enter SSN: 123456789 Filing Status (1-Single, 2-Married Joint, 3-Head of Household, 4-Married Separate): 1 Gross Income: 8640.10 Deductions (-1 if none): 550.00 Taxable income: $-3359.90 Tax rate: 10% Tax obligation: $0.00
HitBox
Add code to HitBox.cpp to complete the hitbox() function definition.
A Rect struct definition is provided which contains four fields:
- x - the leftmost x coordinate (double)
- y - the bottom y coordinate (double)
- width - the width of the rectangle (double)
- height - the height of the rectangle (double)
Thus the rectangle extents will go from x to x+width and y to y+height.
The provided main function will create several different Rect variable pair tests and pass them to the hitbox() function and test the return value, i.e. DO NOT modify main().
The hitbox() function should take two Rect parameters and return a double value indicating the area of overlap between the two rectangles. The function should return 0 if the rectangles do not overlap.
Hint: To determine if two rectangles overlap, check if the edges of one rectangle (which could be either) are within the extents of the other to determine the extents (min and max x/y) of the overlapping rectangle. You will want to check x and y separately and consider the different cases that can occur.
When you are ready to compile the program, in the Cygwin window type the command
make HitBox
To run the program, type the command
./HitBox.exe
You will either see the output (note there is no user input)
All tests passed!
Or an error message indicating which test failed. You may want to sketch the rectangles for any tests that are failing to see what your logic is computing to compare against the value specified in the assert statement.
Grading
Your grade will be determined as follows:
- TaxTime: 50
- HitBox: 50
We expect you to use good coding style. Points may be deducted for poor variable names, inconsistent or missing indentation, and/or lack of comments.
Submitting
To submit your code, make sure your TaxTime.cpp and HitBox.cpp files are saved, and in the Cygwin window type
make submit
Enter your Marmoset username and password (which you should have received by email.) Note that your password will not be echoed to the screen. Make sure that after you enter your username and password, you see a message indicating that the submission was successful.
Make sure that you check the file(s) you submitted to ensure that they are correct. See the instructions for Verifying your submission.
