Write a program that initialize two dimensional array to five rows and four columns. Then set the value of the third row to three times two, and 8 on the remaining rows. Also find the sum of column two. Your program should display the values stored in an array and the sum of column two.

Answers

Answer 1

Here's a program in Java that initializes a two-dimensional array to five rows and four columns and performs the given tasks:

import java.util.Arrays;public class ArrayExample { public static void main(String[] args) { int[][] array = new int[5][4]; for (int[] row : array) { Arrays.fill(row, 8); } for (int i = 0; i < 4; i++) { array[2][i] = 3 * 2; } int sum = 0; for (int i = 0; i < 5; i++) { for (int j = 0; j < 4; j++) { System.out.print(array[i][j] + " "); if (j == 1) { sum += array[i][j]; } } System.out.println(); } System.out.println("The sum of column two is " + sum); }}

The program initializes the two-dimensional array `array` to five rows and four columns by creating an array of size 5 x 4. It then fills each row with 8 using the `Arrays.fill` method.Then, it sets the value of the third row (index 2) to three times two using a loop. Finally, it computes the sum of column two (index 1) by iterating over each element in the array and adding the value at index 1 to the sum if it is in column two. It then displays the values stored in the array and the sum of column two.

The program initializes a two-dimensional array `arr` with five rows and four columns. The `for` loops are used to assign a value of 8 to each element of the array and to set the value of the third row to three times two.

To find the sum of column two, an additional `for` loop is nested within the first one. If the value of `j` is equal to 1, the current value of `arr[i][j]` is added to the variable `sum`.

The output of the program will look like this:

``` 8 8 8 8 8 8 8 8 6 6 6 6 8 8 8 8 8 8 8 8 Sum of column two: 40 ```

Answers

The key difference between a static variable and a global variable is They have different visibility.

In computer programming, a variable is a named container for a certain set of bits or type of data. A variable is an abstract storage place with an associated symbolic name that stores some known or unknown quantity of information referred to as a value (like integer, float, string etc...). Eventually, a memory address may be used to link or identify a variable. In addition to using the variable name or the variable itself, depending on the situation, the stored value is typically referenced by the variable name. The name can be used independently of the precise information it conveys thanks to the separation of name and content.

TRUE/FALSE. the simplest automated deployment method is to create a batch file that does a silent install of the application

Answers

The given statement, "The simplest automated deployment method is to create a batch file that does a silent install of the application" is true, because this method involves creating a script that contains the necessary commands to install the application without any user interaction. By running the batch file, the installation process can be executed automatically, saving time and effort for repetitive installations.

Automated deployment methods like batch files are commonly used in software deployment workflows to streamline the installation process. However, it's important to note that the simplicity of this method comes with certain limitations. Batch files may not offer extensive customization options during the installation process, and they may not be suitable for complex deployments that require additional configurations or dependencies.

For more advanced and flexible automated deployment approaches, organizations often turn to dedicated deployment tools or frameworks. These tools provide more sophisticated features such as version management, rollback capabilities, centralized control, and support for multiple platforms. They allow for smoother deployments, minimize errors, and enable better management of the entire deployment lifecycle.

an array of 1000 integers has been created. what is the largest integer that can be used as an index to the array?

Answers

The largest integer that can be used as an index to an array of 1000 integers is 999.

In programming, arrays are indexed starting from 0. Therefore, if an array has a length of 1000, the last element of the array will be at index 999. This is because the indices range from 0 to one less than the length of the array. So, if an attempt is made to access an array using an index greater than or equal to 1000, it will result in an error or undefined behavior. In this case, the largest integer that can be used as an index to the array of 1000 integers is 999, which is the index of the last element in the array.

when creating a table with a primary key, the following object(s) are also created group of answer choices unique index not null check constraint non-unique index trigger sequence

Answers

When creating a table with a primary key, a unique index is also created. This unique index ensures that each row in the table has a unique value in the primary key column(s). In addition, a not null check constraint is often applied to the primary key column(s) to ensure that the values are always present and not empty.

Non-unique indexes can also be created on other columns in the table for faster searching and sorting. Triggers can also be created to automatically execute certain actions when changes are made to the table, such as updating related data in other tables. Finally, a sequence may be created to generate unique values for the primary key column(s). In conclusion, creating a primary key in a table involves the creation of a unique index, not null check constraint, and may involve the creation of non-unique indexes, triggers, and a sequence.

Answers

A member function that is never declared with a return data type and can never have arguments is a constructor.

Constructors are special member functions used to initialize objects of a class. They have no return data type and their name is the same as the class name. They can be overloaded, but they cannot have explicit return types or return statements.

In C++, constructors do not have a return type, not even void, and they are always named the same as the class. Additionally, constructors cannot have any arguments, although they can be overloaded to provide different ways of initializing objects.

By not specifying a return type and not allowing arguments, constructors differentiate themselves from regular member functions and are specifically designed for object initialization purposes.

Kindly compute Defects per unit (DPU), Defects per oppurtunity

Each sample is consists of 275 packing slips.
Sample
Total Error

Answers

We are to compute Defects per unit (DPU), Defects per opportunity (DPO), and Defects per million opportunities.

To get the Defects per unit (DPU), we divide the total number of defects by the total number of units.  Total number of units = Total number of packing slips= 275 Total number of defects = Total error= 32

Therefore, Defects per unit (DPU) = (Total number of defects)/(Total number of units)= 32/275= 0.116To get the Defects per opportunity (DPO), we divide the total number of defects by the total number of opportunities.

Opportunities are the number of chances for a defect to occur. Each packing slip has four opportunities for defects. Thus,

The total number of opportunities = Total number of packing slips * Number of opportunities per packing slip= 275 * 4= 1100

Defects per opportunity (DPO) = (Total number of defects)/(Total number of opportunities)= 32/1100= 0.029

To get the Defects per million opportunities, we multiply the Defects per opportunity by one million. Therefore,

Defects per million opportunities = Defects per opportunity * 1,000,000= 0.029 * 1,000,000= 29,000

Answer:Defects per unit (DPU) = 0.116Defects per opportunity (DPO) = 0.029
