"Gambling Greg" Assignment

Outcomes:

• Demonstrate the ability to create and use structs
• Demonstrate the ability to create and use menus
• Demonstrate the ability to create and use an array of structs
• Demonstrate the ability to generate and use random numbers

Program Specifications:

Assume that gambling Greg often goes to the Dog Racing Track. Greg loves to bet on the puppies. In each race Greg will place a wager and pick a dog. The dog information will be stored in a structure name DOG as follows:

Name, amount to pay out if Greg wins, and the odds of this dog winning the race.

The program should have the following menu:

[G]amble

[R]esults of All Races

[L]eave the Dog Track

If Greg selects [G] the program will ask Greg for his wager and allow Greg to pick a dog from a list. The program will then run the race. The result will be shown to Greg. The results of the race will be stored for future use.

If Greg selects [R] the program will show Greg the results of all previous races entered during this run of the program.

If Greg selects [L] the program will end.

The dogs:

You will create 9 different dogs. See below:

As you know, the number of days in each month of our calendar varies: • February has 29 days in a leap year, or 28 days otherwise. • April, June, September, and November have 30 days. • All other months have 31 days. Usually, years that are divisible by 4 (e.g., 2008, 2012, 2016) are leap years. However, there’s an exception: years that are divisible by 100 (e.g., 2100, 2200) are not leap years. But there’s also an exception to that exception: years that are divisible by 400 (e.g., 1600, 2000) are leap years.
Within your Lab3HW folder, write a program named DaysInMonth.java that asks the user to enter a month (1-12) and year (1000-3000). Your program should then show the number of days in that month. If the user enters a month or year beyond the specified ranges, show an appropriate error message.
Here are some examples of what your completed program might look like when you run it. Underlined parts indicate what you type in as the program is running.
Example 1
Enter month (1-12): 0 Enter year (1000-3000): 2001 Error - month and/or year out of bounds.
1
Example 2
Enter month (1-12): 2 Enter year (1000-3000): 2016 2/2016 contains 29 days.
Example 3
Enter month (1-12): 2 Enter year (1000-3000): 2900 2/2900 contains 28 days.

Problem

Write in drjava is fine.

Using the classes from Assignment #2, do the following:

1. Modify the parent class (Plant) by adding the following abstract methods:
   1. a method to return the botanical (Latin) name of the plant
   2. a method that describes how the plant is used by humans (as food, to build houses, etc)
2. Add a Vegetable class with a flavor variable (sweet, salty, tart, etc) and 2 methods that return the following information:
   1. list 2 dishes (meals) that the vegetable can be used in
   2. where this vegetable is grown

The Vegetable class should have the usual constructors (default and parameterized), get (accessor) and set (mutator) methods for each attribute, and a toString method

Child classes should call parent methods whenever possible to minimize code duplication.

The driver program must test all the methods in the Vegetable class, and show that the new methods added to the Plant class can be called by each of the child classes. Include comments in your output to describe what you are testing, for example   System.out.println(“testing Plant toString, accessor and mutator”);. Print out some blank lines in the output to make it easier to read and understand what is being output.

Assignment Submission:

Submit a print-out of the Plant and Vegetable classes, the driver file and a sample of the output. Also include a UML diagram of the classes involved. (Use tables in Word to create the various classes. Remember to use the correct arrows between the classes)

Marking Checklist

1. Does EACH class have all the usual methods?
2. Are all methods in EACH class tested, including child objects calling inherited parent methods?
3. Does the child class call the parent’s constructor?
4. Does the child class override the parent’s toString?
5. Does the output produced have lots of comments explaining what is being output?
6. Does each class, and the output, have blank lines and appropriate indenting to make them more readable?

Modify the following C++ program to count the number of correct and incorrect responses typed by the student. After the student types 5 answers, your program should calculate the percentage of correct responses. If the percentage is lower than 75 percent, your program should print “Please ask for extra help” and then terminate. If the percentage is 75 percent or higher, your program should print “Good work!” and then terminate. The program is as follows:

#include<iostream>

#include<iomanip>

#include<cstdlib>

#include<time.h>

using namespace std;

int main()
{
const int no_runs = 5;
int run, n1,n2,answer;

srand((unsigned int)time(NULL));

for(run = 0;run<no_runs;run++)
{
n1 = rand()%9 + 1;
n2 = rand()%9 +1;
while(true)
{
cout<<"What is the product of "<<n1<<" and "<<n2<<": ";
cin>>answer;
if(answer==n1*n2)
break;
cout<<"No. Please try again."<<endl;
}
cout<<"Very good!"<<endl;
}
system("pause");
return 0;
}

*******FOR A BIG THUMBS UP********

------INSTRUCTIONS---------

Coding standards note: The coding standards are in a document in a D2L module titled Coding Standards. See Grading Criteria for points lost if not followed.

Competencies being graded:

1. Ability to implement a HashMap
2. Ability to populate and print from a HashMap
3. Ability to write items from a HashMap
4. Read and write a binary file using ObjectInputStream and ObjectOutputStream
5. Ability to read an English language problem description and design a multi class solution in Java
6. Ability to follow given coding standards- in D2L content under Coding Standards.

Problem Statement:

Create a program that reads in the file people.dat from Homework 2. (Yes, you can use the code from Homework 1). Please make sure to include Person.java in your submission.

Implement your own HashMap implementation. You may use the HashMap example provided in the notes, but you MUST modify it to handle Person objects only and bring it completely up to coding standards to receive all points. You MAY NOT use java.util.HashMap or java.util.TreeMap in this problem.

After reading in the Person objects, store the Personobjects into your HashMap implementation using the unique ID as the key to the map rather than the ArrayList used in Homework 2. Then print the Person objects from the HashMap in a user friendly fashion. You may use iterator or for-each loop-> DO NOT JUST System.out.println THE HASHMAP- ITERATE THROUGH IT.   Hint: Modify your toString in Person to get a nice looking output.

IN PSEUDOCODE and C++

Program 1: Stay on the Screen! Animation in video games is just like animation in movies – it’s drawn image by image (called “frames”). Before the game can draw a frame, it needs to update the position of the objects based on their velocities (among other things). To do that is relatively simple: add the velocity to the position of the object each frame.

For this program, imagine we want to track an object and detect if it goes off the left or right side of the screen (that is, it’s X position is less than 0 and greater than the width of the screen, say, 100). Write a program that asks the user for the starting X and Y position of the object as well as the starting X and Y velocity, then prints out its position each frame until the object moves off of the screen. Design (pseudocode) and implement (source code) for this program.

Sample run 1:

Enter the starting X position: 50

Enter the starting Y position: 50

Enter the starting X velocity: 4.7

Enter the starting Y velocity: 2

JAVA PROGRAMMING ASSIGNMENT - MUST USE ARRAYLIST TO SOLVE. OUTPUT MUST BE EXACT SAME FORMAT AS SAMPLE OUTPUT.

In this assignment, you will create a program implementing the functionalities of a standard queue in a class called Queue3503. You will test the functionalities of the Queue3503 class from the main() method of the Main class. In a queue, first inserted items are removed first and the last items are removed at the end (imagine a line to buy tickets at a ticket counter).

The Queue3503 class will contain:

a. An int[] data filed named elements to store the int values in the queue.

b. An int data field named size that stores the number of elements in the queue.

c. A no-arg constructor that creates a Queue object with default capacity 0.

d. A constructor that takes an int argument representing the capacity of the queue.

e. A method with signature enqueue(int v) that adds the int element v into the queue.

f. A method with signature dequeue() that removes and returns the first element of the queue.

g. A method with signature empty() that returns true if the queue is empty. h. A method with signature getSize() that returns the size of the queue (return type is hence int)).

The queue class you develop should be tested using the following steps: (In other words, your program named Main will consist of the following)

a. Start your queue with an initial capacity of 8.

b. When the dequeue() method is called, an element from the queue at the beginning of the queue must be removed.

c. The main() method in your Main class should consist of statements to:

i. Create a queue object;

ii. Call enqueue() to insert twenty integers (taken from the user) into the queue.

iii. After the above task is completed, include a for-loop that will print out the contents of the queue.

d. After printing the queue filled with twenty integers, call dequeue() repeatedly to remove the beginning element of the queue.

e. Print the contents of the queue after removing every fifth number.

f. For your reference, the execution of the Main program is shown below. User inputs for populating the Queue is shown in the first line. Next, your program outputs are shown.

Sample Run

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

Initial content: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

After removing 5 elements: 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

After removing 5 elements: 11 12 13 14 15 16 17 18 19 20

After removing 5 elements: 16 17 18 19

Please, write code in c++. Using iostream library

Most modern text editors are able to give some statistics about the text they are editing. One nice statistic is the average word length in the text. A word is a maximal continuous sequence of letters ('a'-'z', 'A'-'Z'). Words can be separated by spaces, digits, and punctuation marks. The average word length is the sum of all the words' lengths divided by the total number of words.

For example, in the text "This is div2 easy problem". There are 5 words: "This"is"div"easy" and "problem". The sum of the word lengths is 4+2+3+4+7 = 20, so the average word length is 20/5 = 4.

Given a text, return the average word length in it. If there are no words in the text, return 0.0.

Input
The first line will contain the text of length between 0 and 50 characters inclusive. Text will contain only letters ('a'-'z', 'A'-'Z'), digits ('0'-'9'), spaces, and the following punctuation marks: ',', '.', '?', '!', '-'. The end of text will be marked with symbol '#' (see examples for clarification).

Output
Output should contain one number - the average length. The returned value must be accurate to within a relative or absolute value of 10^-9.

Samples:

Write a Scheme function that takes two integers and returns the list of all integer numbers between these two integers (inclusively) in increasing order. (numbers 10 20) (10 11 12 13 14 15 16 17 18 19 20)

Please explain every step.

C++, Need to create a code that will calculated the statistics for character input?

This is the prompt for the code. I truly understand nothing of what it's asking.

Ask the user for one character (terminated by a carriage return).Using flow control, classify the character into one of these categories:

1)           vowel

2)           consonant

3)           digit (0-9)

4)           other

Output the character input, its numeric decimal value, and the classification. Total up the number of each type of character entered. After the character is entered, ask the user if they want to continue (Y/N). When they enter N, you can stop prompting for more characters. Make sure to validate for Y or N data entry. Then display the total number of each type of characters entered.
