In a file called pp7c.cpp, write a function called
printMoney that has one parameter, a double, and it prints
this parameter out formatted like a dollar amount with $ and
exactly 2 digits to the right of the decimal. Write a driver that
declares an array of monetary amounts like this:
double amounts[MAX_AMOUNTS];
and uses a while or do while loop to ask the user for monetary
amounts with -1 for the amount as a sentinel value to put values in
the array, amounts. Do not allow the user to enter more than
MAX_AMOUNTS numbers. This loop must count how many numbers are
placed in the amounts array as the array may be partially filled.
After using a do or do while loop to fill the array, write a for
loop to call the printMoney function to print all of the
values in the amounts array. The constant and function declarations
are shown below.
const int MAX_AMOUNTS = 10;
void printMoney( double m );

Perform SVM training and testing using SMS spam data set spam.csv . The objective is the predict the class of a new SMS using SVM classifier. The data set is a collection of a set of SMS tagged messages that have been collected for SMS Spam research. It contains one set of SMS messages in English of 5,574 messages, tagged according being ham (legitimate) or spam. The files contain one message per line. Each line is composed by two columns: v1 contains the label (ham or spam) and v2 contains the raw text.
Data set: The details of learning and testing task is as follows:
1. Understand distribution of classes in the data set using suitable plots.
2. Plot distribution of frequent words under “spam" and “ham" classes.
3. Preprocess the data set if required.
4. Apply SVM classifier.
5. Use Cross validation and Hold-out approaches to learn and evaluate SVM classifier.
6. Discuss results achieved by SVM classifier using confusion matrix, sensitivity, specificity and accuracy.

Write a python program that has:
CivilIdNumber
Name
Telephone#
Address
CivilIdNumber
Name
Telephone#
Address
CivilIdNumber
Name
Telephone#
Address
Etc
A record always consists of 4 lines (civilid, name, telephone and address). You can find a sample input file on last page of this assignment, copy it and past it into a .txt file and save it to the same directory that your python program resides on.
The function then creates a dictionary with the civilIdNuber as the key and the rest of the record as a list with index 0 being the name, index 1 being the telephone# and index 2 being Address.
When finishing reading all records the function then returns the dictionary
CivilId: civilidnumber
Name: name
Address: address
Telephone Number: telephone
CivilId: civilidnumber
Name: name
Address: address
Telephone Number: telephone
Etc…

Henry Magruder made a mistake—he left a CD at the coffee station. Later, when Iris Majwubu was topping off her mug with fresh tea, hoping to wrap up her work on the current SQL code module before it was time to go home, she saw the unlabeled CD on the counter. Being the helpful sort, she picked it up, intending to return it to the person who’d left it behind.
Expecting to find perhaps the latest device drivers, or
someone’s work from the development team’s office, Iris slipped the
disk into the drive of her computer and ran a virus scan on its
contents before opening the file explorer program. She had been
correct in assuming the CD contained data files, and lots of them.
She opened a file at random: names, addresses, and Social Security
numbers appeared on her screen. These were not the test records she
expected; they looked more like critical payroll data. Concerned,
she found a readme.txt file
and opened it. It read:
Jill, see files on this disc. Hope they meet your expectations. Wire money to account as arranged. Rest of data sent on payment.
Iris realized that someone was selling sensitive company data to
an outside information
broker. She looked back at the directory listing and saw that the
files spanned the range of every department at Sequential Label and
Supply—everything from customer lists to shipping invoices. She saw
one file that appeared to contain the credit card numbers of every
Web customer the company supplied. She opened another file and saw
that it only contained about half of the relevant data. Whoever did
this had split the data into two parts.
That made sense: payment on delivery of the first half. Now, who did this belong to? She opened up the file properties option on the readme.txt file. The file owner was listed as “hmagruder.” That must be Henry Magruder, the developer two cubes over in the next aisle. Iris pondered her next action.
Iris called the company security hotline. The hotline was an
anonymous way to report any
suspicious activity or abuse of company policy, although Iris chose
to identify herself. The
next morning, she was called to a meeting with an investigator from
corporate security,
which led to more meetings with others in corporate security, and
then finally a meeting with
the director of human resources and Gladys Williams, the CIO of
SLS.
Questions:
1. Why was Iris justified in determining who the owner of the CD
was?
2. Should Iris have approached Henry directly, or was the hotline
the most effective way
to take action? Why do you think so?
3. Should Iris have placed the CD back at the coffee station and
forgotten the whole
thing? Explain why that action would have been ethical or
unethical.

(Java) Create a program using 3 methods. The methods must be public and static. Ask the user for 3 numbers, then call the methods from main to print max, min, and average.
The first method max (int x, int y, int z) returns the maximum value of 3 integer values.
The second method min (int X, int y, int z) returns the minimum value of 3 integer values.
And the third average (int x, int y, int z) returns the average of 3 integer values.
Sample Output: (bold = user input)
Enter # 1: 5
Enter # 2: 9
Enter # 3: 2
Min is 2
Max is 9
Average is 5.33333
Sample output 2
Enter # 1: 45
Enter # 2: 11
Enter # 3: -3
Min is -3
Max is 45
Average is 17.6667
Code Example:
int addTwoNumbers (int x, int y) {
int result = x + y;

1) Create a java class Traveler that has four data members, String name, Date bDate, int id and int noOfDependens.
Generate the following:
1- Getters and Setters.
2- Four parametrize constructor to initialize the four data members above.
3- toString() method.
Create a java class Flight that has four data members, String number, String destination, int capacity, and ArrayList travelers.
Note1 - travelers will be used to track the No. of travelers so far on the selected flight.
Note2 - No. of travelers = No. of dependents + 1;
Generate the following: 1- Getters and Setters.
2- Three parametrize constructor to initialize the number, destination and capacity.
3- toString() method.
4- Method public void addTraveler(Traveler traveler) that will do the following:
a. It will calculate the total No. of travelers so far.
b. It will calculate the total availability = capacity - No. of travelers.
c. If the availability is equal to OR more than the requested tickets (traveler + his noOfDependens) then, accept this reservation and add the traveler to the flight ArrayList, otherwise, reject the reservation by printing the following message “This reservation is NOT accepted. Total No. of requested tickets are: X while the availability is: Y”
d. Sample for your output in case the reservation is accepted is listed below.
Create a java class AppSystem for testing, and include the main method. Then create the following:
