Goal:

After the manager of a local McDonalds hired several ASU grads to work the cash registers, he realized that they were having trouble figuring out the correct amount of change to return to their customers. The manager wants you to create a VB.NET program that calculates the correct amount of change to be given to a customer following a transaction.

Guidelines:

You should have

• Option Explicit On (this forces you to declare all of your variables)
• Option Strict On (this forces you to explicitly convert from one data type to another rather than relying on VB.Net to make these conversions for you implicitly)

• At least one relevant image on your form (lots of McDonalds and $$ images available on the Net)
• Calculate, Clear, and Exit buttons along the bottom of your form

Inputs:

  Transaction Amount

  validation: data must have been entered, data must be numeric, amount cannot be negative or greater than $1000.00

Amount of Cash Provided By The Customer

validation: data must have been entered, data must be numeric,

amount cannot be negative and must be equal to or greater than the Transaction Amount

Outputs:

Total Amount of Change To Be Returned

Number of Twenties To Be Returned

Number of Tens To Be Returned

Number of Fives To Be Returned

Number of Ones To Be Returned

Number of Quarters To Be Returned

Number of Dimes To Be Returned

Number of Nickels To Be Returned

Number of Pennies To Be Returned

Guidelines

Look up one of the many sites describing the BMI, and read a bit about how it is used to indicate general health. Create a VB.Net program that, given a user’s height in inches and weight in pounds, will calculate and display his/her BMI. After calculating the user's BMI, indicate the user's health status.  

BMI = (weight * 703) / (height * height)

Display the user’s Height Status:

Input: Height and Weight.

Output: BMI (to one decimal, like 27.7) and Weight Status (a string, like “Overweight”)

After the remarks at the top of your program, add “Option Explicit On” and “Option Strict On”. The former requires you to explicitly declare each variable used and the latter requires you to explicitly convert data from one type to another, rather than rely on VB.Net to implicitly convert data.

Does anyone know how to find if a certain String is available in an ArrayList?

I was asked by my instructor to make a certain program about Student Record

In the area where I need to add some student in the ArrayList it won't add if there is the same name in the ArrayList

at first I used the equals method and contains method but later I found it was prohibited to use such method.

Is there a way to find if a String is Available in the ArrayList without using the method

Please check on else if(response==2)

1) Convert negative fractional decimal number to 8-bit binary number: – 16.625 (use 2's complement binary format)

Hint: –17 + 0.375

Given the hint above, the fractional number will be divided into two parts,
- Whole number,
- Fractional part, must be positive

Spatial indexing with quadtrees in python

The quadtrees data structure is a special type of tree structure, which can recursively divide a flat 2-D space into four quadrants. Each hierarchical node in this tree structure has either zero or four children. It can be used for various purposes like sparse data storage, image processing, and spatial indexing. Spatial indexing is all about the efficient execution of select geometric queries, forming an essential part of geo-spatial application design. For example, ridesharing applications like Ola and Uber process geo-queries to track the location of cabs and provide updates to users. Facebook’s Nearby Friends feature also has similar functionality. Here, the associated meta-data is stored in the form of tables, and a spatial index is created separately with the object coordinates. The problem objective is to find the nearest point to a given one. You can pursue quadtree data structure projects in a wide range of fields, from mapping, urban planning, and transportation planning to disaster management and mitigation. We have provided a brief outline to fuel your problem-solving and analytical skills. Objective: Creating a data structure that enables the following operations

 Insert a location or geometric space

 Search for the coordinates of a specific location

 Count the number of locations in the data structure in a particular contiguous area

SYSTEM RECOVERY

It is highly probable that eventually something bad will happen to your data or your hardware. What can you do to lessen the impact of these problems? You can look at both hardware and software solutions. What is fault tolerance?

In C++

1. Extend the driver class to do the following:
   1. Declare a vector of circles
   2. Call a function with signature inputData(vector<Circle> &, string filename) that reads data from a file called dataLab4.txt into the vector. The following c-e are done in this function
   3. Use istringstream to create an input string stream called instream. Initialize it with each string that is read from the data file using the getline method.
   4. Read the coordinates for the center and the radius from instream to create the circles
   5. Include a try catch statement to take care of the exception that would occur if there was a file open error. Display the message “File Open Error” and exit if the exception occurs
   6. Display all the circles in this vector using the toString method
   7. Use an iterator to iterate through the vector to display these circles
   8. Display the count of all the circles in the vector using the getCount method
   1. Display the count of all the circles in the vector using the vector size method
   10. Clear the vector
   11. Display the current count of all the circles using the getCount method
   50. Display the current count of all the circles using the vector size method
   1000. Use the cout statements and other helper statements given to you in the template in Zylabs

//otherwise
//use getline to read data line feed to the instream
//create a circle using the data in the instream
//add the circles to the vector

I'm trying to convert between different number representations in C++ , I have the prototype but im not sure what do do from here

bool convertF(double & x, const string & bits);

bits is supposed to be an 8-bit (not 5-bit) value, each char being '0' or '1'; if not, return

false. The first bit of bits represents the sign bit, the next 3 bits represent the exponent,

and the next 4 bits represent the significand.

convertF may assume without checking that the 3 exponent bits are not all the same.

convertF's job is to set x to the floating-point number that bits represents and return

true.

For example, convertF(x, "101011000") should set x to -7/8 == -0.875

Java

Create an abstract Product Class

Add the following private attributes:

• name

• sku (int)

• price (double)

Create getter/setter methods for all attributes

Create a constructor that takes in all attributes and sets them

Remove the default constructor
Override the toString() method and return a String that represents the building object that is formatted

nicely and contains all information (attributes)

Create a FoodProduct Class that extends Product

Add the following private attributes:

• expDate (java.util.Date) for expiration date

• refrigerationTemp (int) if 70 or above, none necessary, otherwise it will be a lower number

• servingSize (int) in grams

• caloriesPerServing (int)

• allergens (ArrayList<String>)

  Create getter/setter methods for all attributes

  Create a constructor that takes in all attributes for product and food product. Call the super constructor and then set the expDate, refrigerationTemp, servingSize, caloriesPerServing and allergens.

• Remove the default constructor

  Override the toString() method and return a String that represents the food product object that is formatted nicely and contains all information (super toString and the private attributes)

Create a CleaningProduct Class that extends Product

Add the following private attributes:

• String chemicalName

• String hazards

• String precautions

• String firstAid

• ArrayList<String> uses (e.g. kitchen, bath, laundry, etc)

Create getter/setter methods for all attributes

Create a constructor that takes in all attributes for product and food product. Call the super constructor and then set the chemical name, hazard, precautions, firstAid and uses. TIP: try generating the constructor, it will add the super stuff for you. (Also, see Lynda inheritance videos.)

Remove the default constructor

Override the toString() method and return a String that represents the cleaning product object that is formatted nicely and contains all information (super toString() and the private attributes)

Create the interface Edible which contains the following method signatures:

• public Date getExpDate();

• public void setRefrigerationTemp(Int refrigerationTemp)

• public int getRefrigerationTemp();

• public void setExpDate(Date expDate) ;

• public int getServingSize() ;

• public void setServingSize(int servingSize) ;

• public int getCaloriesPerServing() ;

• public void setCaloriesPerServing(int caloriesPerServing);

• public String getAllergens() ;

• public void setAllergens(ArrayList<String> allergens) ;

Create the interface Chemical which contains the following method signatures

• public String getChemicalName();

• public void setChemicalName(String chemicalName) ;

• public String getHazards() ;

• public void setHazards(String hazards);

• public String getPrecautions() ;

• public void setPrecautions(String precautions) ;

• public ArrayList<String> getUses() ;

• public void setUses(ArrayList<String> uses) ;

• public String getFirstAid() ;

• public void setFirstAid(String firstAid) ;

Modify the FoodProduct Class to implement Edible, be sure to add the @Override before any methods that were there (get/set methods) that are also in the Edible interface.

Modify the CleaningProduct Class to implement Chemical, be sure to add the @Override before any methods that were there (get/set methods) that are also in the Chemical interface.

Create your main/test class to read products from a file, instantiate them, load them into an ArrayList and then print them nicely to the console at the end of your program. See instructor note about reading the file as the lengths of the lines may be different depending on the list of allergens. It is also comma delimited rather than by spaces. You will have to read an entire line, split its contents and then store the information into variables. The last element(s) are the allergens that you will have to store to an ArrayList.

SYSTEM REQUIREMENTS-

Each dog goes through a six- to ninemonth training regimen before they are put into service. Part of our process is to record and track several data points about the rescue animals.

Dogs are given the status of "intake" before training starts. Once in training, they move through a set of five rigorous phases: Phase I, Phase II, Phase III, Phase IV, and Phase V. While in training, a dog is given the status of its current training phase (e.g., "Phase I"). When a dog graduates from training, it is given the status of "in service" and is eligible for use by clients. If a dog does not successfully make it through training, it is given the status of "farm," indicating that it will live a life of leisure on a Grazioso Salvare farm.

The Animals Through years of experience, we have narrowed the list of dog breeds eligible for rescue training to the following:

• American pit bull terrier • Beagle • Belgian Malinois • Border collie • Bloodhound • Coonhound • English springer spaniel • German shepherd • German shorthaired pointer • Golden retriever • Labrador retriever • Nova Scotia duck tolling retriever • Rough collie • Smooth collie

When we acquire a dog, we record the breed, gender, age, weight, date, and the location where we obtained them. There is usually a short lag time between when we acquire a dog and when they start training, which we document as well. Additionally, we track graduation dates, dates dogs are placed into "service," and details about the dogs' in-service placement (agency, city, country, and name, email address, phone number, and mailing address for the agency's point of contact).
