.Centralized and decentralized service offer some challenges to the food service .what are these challenges and how they are best addressed please explain ?

write the program named Lab06.java that contains the following four static methods:

• public static double max(double[] data) that returns the maximum value in the array data

• public static double min(double[] data) that returns the minimum value in the array data

• public static double sum(double[] data) that sums all items in the array and return the result

• public static double ave(double[] data) that call the sum() method and then return the average.

Once you have completed the methods above, write a simple main program that does the following:

1. Asks the user how many items will be entered

2. Creates an array of double of the correct size

3. Prompts the user and reads in the values

4. Calculates and prints out the max, min, sum, and average using the methods above.

Build a case for and against non-reciprocity principles in developing countries. Be sure to provide a comprehensive rationale for each position and examples.

Im working on modifying my current code to function with these changes below

Create a Java program that meets the following criteria

• You program should contain a “static method” double[] readArray(String filename) which accepts the name of a file to read as a String parameter.
  • This function should read all the values into a new array of “doubles”
    • NOTE: The first value of the file is an integer used to indicate the size of the array that you will need (see above)
  • The function should return the array which was created and read in this method.
    
• You program should contain a function double[] processArray() (double[] dataArray) which accepts the array read by the previous function.
  • This function should scan the array and calculate the following information:
    • The smallest value in the array.
    • The largest value in the array.
    • The average value in the array.
    • The sum of the values in the array.
    • A count of the number of items that are greater than the average value
    • The largest difference between any two adjacent values!
      1. For example, using the above sample input, the largest adjacent difference is between the values 7.876 and 3.1415 (array indexes 2 and 3), which is a difference of 4.7345.
      2. (This one is not terribly difficult, but it will require some thought!)
         
  • The function should return a new array of six values containing the information outlined above in the order shown.
    • For example, using the sample data file above, the array would contain the following values in the following order:
      { 1.23, 7.876, 3.9817, 19.9085, 2.0, 4.7345 }
      
    • The order is just: smallest, largest, average, sum, above average count, largest difference
      
• The main method should:
  • Check to see the user passed a filename to main itself via the (String[] args)
    • If no file name exists, the program should prompt the user to enter a source-file name.
      
  • Call the functions above to read the array and calculate the results.
    
  • Display all the final results for example:
    
    Smallest = 1.23
    Largest = 7.876
    Average = 3.9817
    Sum = 19.9085
    Count of Larger than Average = 2.0
    Largest Difference = 4.7345

My current code is show as below, i was wondering how i would go about doing that im a little lost.

import java.io.File;
import java.util.Scanner;

public class Lab5 {

    public static void main(String[] args) {
        String inFileName;

        if (args.length > 1) {
            inFileName = args[0];
        } else {
            Scanner console = new Scanner(System.in);
            System.out.println("Enter a Filename: ");
            inFileName = console.nextLine();
        }

        double[] myData = readArray(inFileName);
        double[] results = processArray(myData);

        // TODO: Display Results...
    }

    static double[] readArray(String filename) {
        File inFile = new File(filename);

        if (inFile.canRead()) {
            try {
                Scanner fileScanner = new Scanner(inFile);
                int count = fileScanner.nextInt();
                double[] data = new double[count];

                for (int i = 0; i < count; i++) {
                    data[i] = fileScanner.nextDouble();
                }

                return data;
            } catch (Exception e) {
                return new double[0];
            }
        } else {
            System.out.println("Can't read file.");
            return new double[0];
        }
    }

    static double[] processArray(double[] dataArray) {
        // TODO: Implement Functionality from Requirements.
        for (double data : dataArray) {
            System.out.println(data);
        }

        return new double[0];
    }

}

Start with a program that allows the user to input a number of integers, and then stores them in an int array.

Write a function called maxint() that goes through the array, element by element, looking for the largest one.The function should take as arguments the address of the array and the number of elements in it, and return the index number of the largest element. The program should call this function and then display the largest element and its index number.

Update the following C code and write the function :

void sln_stutter(sln_list* li);

that modifies the list li so that it each element is duplicated. For example the list with elements [1,2,3] would after this function call become the list [1,1,2,2,3,3].

I have a list of things for review in C programming, could you please give me an example and a brief explanation for each question... Thank you very much

• 9. Apply pointer arithmetic to C code
• 10. Explain how multiple files can be organized and run in C, as well as what (recommended) content can be placed in header files
• 11. Explain how a link list can be created (i.e. what the nodes are and what components or syntax can be used to create the nodes)

Cyanide ion, CN^-, is important in metal plating industries as well as in leaching matals from ores because it keeps metals dissolved under conditions where they would otherwise form solids (precipitate) and settle out of solution. It is important to maintain pH>10.5 in these solutions to avoid forming toxic hydrogen cyanide gas. If a solution is prepared by dissolving 10^-2M NaCN in water, will the pH be in the region where the solution is safe? What is {HCN} in the solution? The pKa of HCN is 9.24.

in free radical polymerization, wastage reaction are due to

1) Describe the various shapes of synovial joints (e.g. hinge, condyloid, ball and socket, etc.)

2) What types of movements can occur at synovial joints (e.g. gliding, angular, etc.)?

Suppose we want to make a 10 item queue starting from location x4000. In class, we discussed using a HEAD and a TAIL pointer to keep track of the beginning and end of the queue. In fact, we suggested that the HEAD pointer could point to the first element that we would remove from the queue and the TAIL pointer could point the last element that we have added the queue. It turns out that our suggestion does not work.

Part a) What is wrong with our suggestion? (Hint: how do we check if the queue is full? How do we check if it is empty?)

Part b) What simple change could be made to our queue to resolve this problem?

Part c) Using your correction, write a few instructions that check if the queue is full. Use R3 for the HEAD pointer and R4 for the TAIL pointer.

Part d) Using your correction, write a few instructions that check if the queue is empty. Again, using R3 for the HEAD pointer and R4 for the TAIL pointer.

Balancing Redox Equations in Acidic or Basic Solutions

In addition to mass balance, oxidation-reduction reactions must be balanced such that the number of electrons lost in the oxidation equals the number of electrons gained in the reduction. This balancing can be done by two methods. The oxidation number method balances the net increase in oxidation of the substance oxidized with the net decrease in the oxidation number of the substance reduced. The half-reaction method balances the electrons lost in the oxidation half-reaction with the electrons gained in the reduction half-reaction. In both methods

H2O(l),OH?(aq), and H+ (aq) may be added to complete the mass balance. Which substances are used depends on the reaction conditions.

Acidic solution

In acidic solution, bromate ion can be used to react with a number of metal ions. One such reaction is

BrO3?(aq)+Sn2+(aq)?Br?(aq)+Sn4+(aq)

Since this reaction takes place in acidic solution,

H2O(l)andH+(aq) will be involved in the reaction. Places for these species are indicated by the blanks in the following restatement of the equation:

BrO3?(aq)+Sn2+(aq)+ ____ ?Br?(aq)+Sn4+(aq)+ ___

Part A

What are the coefficients of the six species in the balanced equation above? Remember to include coefficients for

H2O(l)andH+(aq)

in the appropriate blanks.

Enter the equation coefficients in order separated by commas (e.g., 2,2,1,4,4,3).

Basic solution

Potassium permanganate,

KMnO4, is a powerful oxidizing agent. The products of a given redox reaction with the permanganate ion depend on the reaction conditions used. In basic solution, the following equation represents the reaction of this ion with a solution containing sodium sulfite:

MnO4?(aq)+SO32?(aq)?MnO2(s)+SO42?(aq)Since this reaction takes place in basic solution,H2O(l)andOH?(aq)

will be shown in the reaction. Places for these species are indicated by the blanks in the following restatement of the equation:

MnO4?(aq)+SO32?(aq)+ ____?MnO2(s)+SO42?(aq)+ ___

Part B

What are the coefficients of the six species in the balanced equation above? Remember to include coefficients for

H2O(l)andOH? (aq) in the blanks where appropriate.

Enter the equation coefficients in order separated by commas (e.g., 2,2,1,4,4,3).
