Display the shortest words in a sentence in JAVA

Write a method that displays all the shortest words in a given sentence. You are not allowed to use array

In the main method, ask the user to enter a sentence and call the method above to display all the shortest words in a given sentence.

You must design the algorithms for both the programmer-defined method and the main method.

Leave comments on code describing what does what

Objectives:

1. To introduce pointer variables and their relationship with arrays

2. To introduce the dereferencing operator

3. To introduce the concept of dynamic memory allocation

A distinction must always be made between a memory location’s address and the data stored at that location. In this lab, we will look at addresses of variables and at special variables, called pointers, which hold these addresses.

The address of a variable is given by preceding the variable name with the C++ address operator (&). The & operator in front of the variable sum indicates that the address itself, and not the data stored in that location.

cout << &sum; // This outputs the address of the variable sum

To define a variable to be a pointer, we precede it with an asterisk (*). The asterisk in front of the variable indicates that ptr holds the address of a memory location.

int *ptr;

The int indicates that the memory location that ptr points to holds integer values. ptr is NOT an integer data type, but rather a pointer that holds the address of a location where an integer value is stored.

Explain the difference between the following two statements:

  

int sum; // ____________________________

int *sumPtr; // ___________________________

Using the symbols * and &:

1. The & symbol is basically used on two occasions.

• reference variable : The memory address of the parameter is sent to the function instead of the value at that address.

• address of a variable

void swap (int &first, int &second) // The & indicates that the parameters

{ // first and second are being passed by reference.

int temp;

temp = first; // Since first is a reference variable,

// the compiler retrieves the value

// stored there and places it in temp.

first = second // New values are written directly into

second = temp; // the memory locations of first and second.

}

   

2) The * symbol is used on

• define pointer variables:

• the contents of the memory location

int *ptr;

Experiment 1

Step 1:

Complete this program by filling in the code (places in bold). Note: use only pointer variables when instructed to by the comments in bold. This program is to test your knowledge of pointer variables and the & and * symbols.

Step 2:

Run the program with the following data: 10 15. Record the output here .

// This program demonstrates the use of pointer variables

// It finds the area of a rectangle given length and width

// It prints the length and width in ascending order

#include <iostream>

using namespace std;

int main()

{

int length; // holds length

int width; // holds width

int area; // holds area

int *lengthPtr; // int pointer which will be set to point to length

int *widthPtr; // int pointer which will be set to point to width

  cout << "Please input the length of the rectangle" << endl;

cin >> length;

cout << "Please input the width of the rectangle" << endl;

cin >> width;

// Fill in code to make lengthPtr point to length (hold its address)

// Fill in code to make widthPtr point to width (hold its address)

area = // Fill in code to find the area by using only the pointer variables

cout << "The area is " << area << endl;

if (// Fill in the condition length > width by using only the pointer variables)

cout << "The length is greater than the width" << endl;

else if (// Fill in the condition of width > length by using only the pointer

// variables)

cout << "The width is greater than the length" << endl;

else

cout << "The width and length are the same" << endl;

return 0;

}

Experiment 2: Dynamic Memory

Step 1:

Complete the program by filling in the code. (Areas in bold) This problem requires that you study very carefully. The code has already written to prepare you to complete the program.

Step 2:

In inputting and outputting the name, you were asked NOT to use a bracketed subscript. Why is a bracketed subscript unnecessary? Would using name [pos] work for inputting the name? Why or why not? Would using name [pos] work for outputting the name? Why or why not?

Try them both and see.

// This program demonstrates the use of dynamic variables

#include <iostream>

using namespace std;

const int MAXNAME = 10;

int main()

{

int pos;

char * name;

int * one;

int * two;

int * three;

int result;

// Fill in code to allocate the integer variable one here

// Fill in code to allocate the integer variable two here

// Fill in code to allocate the integer variable three here

// Fill in code to allocate the character array pointed to by name

cout << "Enter your last name with exactly 10 characters." << endl;

cout << "If your name has < 10 characters, repeat last letter. " << endl

<< "Blanks at the end do not count." << endl;

for (pos = 0; pos < MAXNAME; pos++)

cin >> // Fill in code to read a character into the name array // WITHOUT USING a bracketed subscript

cout << "Hi ";

for (pos = 0; pos < MAXNAME; pos++)

cout << // Fill in code to a print a character from the name array // WITHOUT USING a bracketed subscript

cout << endl << "Enter three integer numbers separated by blanks" << endl;

// Fill in code to input three numbers and store them in the

// dynamic variables pointed to by pointers one, two, and three.

// You are working only with pointer variables

//echo print

cout << "The three numbers are " << endl;

// Fill in code to output those numbers

result = // Fill in code to calculate the sum of the three numbers

cout << "The sum of the three values is " << result << endl;

// Fill in code to deallocate one, two, three and name

return 0;

}

Sample Run:

Enter your last name with exactly 10 characters.

If your name < 10 characters, repeat last letter. Blanks do not count.

DeFinooooo

Hi DeFinooooo

Enter three integer numbers separated by blanks

5 6 7

The three numbers are 5 6 7

The sum of the three values is 18

Experiment 3: Dynamic Arrays

Question: Fill in the code as indicated by the comments in bold.

// This program demonstrates the use of dynamic arrays

#include <iostream>

#include <iomanip>

using namespace std;

int main()

{

float *monthSales; // a pointer used to point to an array

// holding monthly sales

float total = 0; // total of all sales

float average; // average of monthly sales

int numOfSales; // number of sales to be processed

int count; // loop counter

cout << fixed << showpoint << setprecision(2);

cout << "How many monthly sales will be processed? ";

cin >> numOfSales;

// Fill in the code to allocate memory for the array pointed to by

// monthSales.

if ( // Fill in the condition to determine if memory has been

// allocated (or eliminate this if construct if your instructor

// tells you it is not needed for your compiler)

)

{

cout << "Error allocating memory!\n";

return 1;

}

cout << "Enter the sales below\n";

for (count = 0; count < numOfSales; count++)

{

cout << "Sales for Month number "

<< // Fill in code to show the number of the month

<< ":";

// Fill in code to bring sales into an element of the array

}

for (count = 0; count < numOfSales; count++)

{

total = total + monthSales[count];

}

average = // Fill in code to find the average

cout << "Average Monthly sale is $" << average << endl;

// Fill in the code to deallocate memory assigned to the array.

return 0;

}

Sample Run:

How many monthly sales will be processed 3

Enter the sales below

Sales for Month number 1: 401.25

Sales for Month number 2: 352.89

Sales for Month number 3: 375.05

Average Monthly sale is $376.40

You must evaluate the purchase of a proposed spectrometer for the R&D department. The base price is $300,000, and it would cost another $60,000 to modify the equipment for special use by the firm. The equipment falls into the MACRS 3-year class and would be sold after 3 years for $150,000. The applicable depreciation rates are 33%, 45%, 15%, and 7%. The equipment would require a $10,000 increase in net operating working capital (spare parts inventory). The project would have no effect on revenues, but it should save the firm $60,000 per year in before-tax labor costs. The firm's marginal federal-plus-state tax rate is 40%.

1. What is the initial investment outlay for the spectrometer, that is, what is the Year 0 project cash flow? Round your answer to the nearest cent. Negative amount should be indicated by a minus sign.
   $

2. What are the project's annual cash flows in Years 1, 2, and 3? Round your answers to the nearest cent.

int[][] BingoCardArray = new int[5][5];

Use a nested for-loop, to populate the 2-D array representing 5 columns for B – I – N – G – O, where
row 1 =
        col 1 = random # 1- 15
        col 2 = random # 16 – 30
        col 3 = random # 31 – 45
        col 4 = random # 46 – 60
        col 5 = random # 61 – 75

row 2 =
        col 1 = random # 1- 15
        col 2 = random # 16 – 30
        col 3 = random # 31 – 45
        col 4 = random # 46 – 60
        col 5 = random # 61 - 75

row 3 =
        col 1 = random # 1- 15
        col 2 = random # 16 – 30
        col 3 = random # 31 – 45
        col 4 = random # 46 – 60
        col 5 = random # 61 – 75

row 4 =
        col 1 = random # 1- 15
        col 2 = random # 16 – 30
        col 3 = random # 31 – 45
        col 4 = random # 46 – 60
        col 5 = random # 61 - 75

row 5 =
        col 1 = random # 1- 15
        col 2 = random # 16 – 30
        col 3 = random # 31 – 45
        col 4 = random # 46 – 60
        col 5 = random # 61 – 75

The playGame()method in the BingoGame (Driver) class will loop to generate 50 random numbers in the range of 1 to 75.  This simulates drawing 50 numbers in a BINGO game.  The method will pass the number to a method, checkBingo()in the domain class, BingoCard, which will check if the number received as a parameter is in the B range (1 – 15), I range (16 – 30), N range (31 – 45), G range (46 -60) or O range (61 – 75).  According to the range it is in, the method will check each of the cells in designated column (col 0 = B; col 1 = I; col 2 = N; col 3 = G; col 4 = O).  Example: randomNum 27 was randomly generated, which belongs to the I-range, column 1, checking rows 0 to 4.

for (int row = 0; row <= 4; row++)
{  
     //hard-code column 1 since checking I-column:
    if (randomNum == BingoCardArray[row][1])

    {
             BingoCardArray[row][1] = 0;
    }
}

etc.    //the 0 being moved to the number simulates putting a chip on the Bingo card, marking that the
          // number was called.

The gotBingo()method in the Bingo (Domain) class will return TRUE if 5 numbers were set to 0 either horizontally, vertically, or diagonally.  Otherwise, the method will return FALSE.

Each horizontal checkis a set of if-else if statements

for (int row = 0; row < 5; row++)
{
     int rowTotal = 0;

     for (int col = 0; col < 5; col++)
    {

           //add up all the column values in that row, and see if they add up to 0.

           ….

     }

}

Each vertical checkis a set of if-else if statements

for (int col = 0; col  < 5; col++)
{
     int colTotal = 0;

     for (int row = 0; row < 5; row++)
    {

           //add up all the row values in that column, and see if they add up to 0.

           ….

     }

}

//for diagonals check….
for (int row = 0; row < 5; row++)
{
     int diagonal1Total = 0;

     int diagonal2Total = 0;

     for (int col = 0; col < 5; col++)
    {

           //figure out if it is a diagonal going one way

           //figure out if it is a diagonal going the other way

           ….

     }

}

When gotBingo()ends, it will have either returned a TRUE or a FALSE.

In the driver class, the totalGamesWon is a global variable for keeping track of how many games the user wins instead of the computer. Before the

The determineWinner()method in the Bingo (Driver) class will call the gotBIngo() method in the domain class, and if it returns true, it will add 1 to the totalGamesWon, otherwise it will leave the totalGamesWon alone.

Finally, the mainmethod will contain a do-while loop that will execute at least once, and do the following:

1. Instantiate the BingoCard class into an object
2. Call the playGame() method in the driver class
3. The playGame() method will call the checkBingo(int aNum) in the domain class
4. Call the determineWinner() method in the driver class, which calls the gotBingo() method in the domain class, and add 1 to totalGamesWom whenever gotBingo() returns true.
5. Ask user if he/she wants to repeat and play BINGO again.

Problem

Design and implement these 4 files:

1. A parent class called Plant with name (eg Rose, Douglas Fir) and lifespan (could be in days, weeks, months or years) attributes
2. Tree inherits from Plant and adds a height attribute
3. Flower inherits from Plant and adds a color attribute
4. A driver file to test the 3 classes above.

The classes described in #1, 2 and 3 above 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 each of the 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 each class file, the driver file and a sample of the output.

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?

Accounting Information System

Program using java

Take user input and give corresponding output.

A user is considering different options of operating air conditioning.

Depending on room temperature (here, room temperature is given by user), this program should give different instructions.

There are three scenarios.

- If temperature is above 90, the program should output “cooling”.

-If the temperature is below 70, the program should output “heating”.

-Otherwise, the program should output “stopped”.

For example, if user enters “95”, this is how the program should look like:

Please enter room temperature: 95

Air conditioning is cooling.

1. You are offered with a partial specification of a 4x5 2-D array. The partial specification is shown as follows. (Only the first row and the first column are specified.)

-1   -2   -3   -4   -5

-6

-11

-16

You are required to write a C program to perform two tasks.

1. First, to write a sequence of C codes to generate the values for the unspecified elements in the 4x5 2-D array. The array is called A. The row index is denoted by i, and column index is denoted by j. i, j starts from 0. Namely, for first row, i = 0. For first column, j = 0. The values of the unspecified elements are defined as

A[i][j] = A[i-1][j]*A[i][j-1] for i > 0 and for j > 0.

After all elements in the 4x5 2-D array are fully specified, print out the content of the entire 4x5 2-D array according to the format shown below.
