2 Programming Exercises 2.1 Write an interactive C# program that includes a named constant repre- senting next year's anticipated 20% raise for each employee in a company. Now, declare a variable to represent the current salary of an employee that ac- cepts user input, and display, with explanatory text, the old salary, the value of the raise, and the new salary for the employee. A sample run follows.
Enter your name: John Hello John! Enter your current salary: 2008 old salary is $2000 plus $400 raise equals $2400 as a new salary! Press any key to continue ,
Answers
Answer:
using System;
class ProjectedRaises {
static void Main() {
const float raise = 0.04f;
double salary1 = 0.0f,salary2 = 0.0f,salary3 = 0.0f;
Console.WriteLine("Current salary for each employee: ");
salary1 = Single.Parse(Console.ReadLine());
salary2 = Single.Parse(Console.ReadLine());
salary3 = Single.Parse(Console.ReadLine());
salary1 = salary1 + raise * salary1;
salary2 = salary2 + raise * salary2;
salary3 = salary3 + raise * salary3;
Console.WriteLine("Next year salary for the employees are: ");
Console.WriteLine(Math.Round(salary1));
Console.WriteLine(Math.Round(salary2));
Console.WriteLine(Math.Round(salary3));
}
}
Explanation:
This declares and initializes variable raise as a float constant
const float raise = 0.04f;
This declares the salary of each employee as double
double salary1 = 0.0f,salary2 = 0.0f,salary3 = 0.0f;
This prompts the user for the salaries of the employee
Console.WriteLine("Current salary for each employee: ");
The next three lines get the salary of the employees
salary1 = Single.Parse(Console.ReadLine());
salary2 = Single.Parse(Console.ReadLine());
salary3 = Single.Parse(Console.ReadLine());
The next three lines calculate the new salaries of the employees
salary1 = salary1 + raise * salary1;
salary2 = salary2 + raise * salary2;
salary3 = salary3 + raise * salary3;
This prints the header
Console.WriteLine("Next year salary for the employees are: ");
The next three lines print the new salaries of the employees
Console.WriteLine(Math.Round(salary1));
Console.WriteLine(Math.Round(salary2));
Console.WriteLine(Math.Round(salary3));

What is the main difference between sequential and parallel computing?
Answers
Answer:
In sequential composition, different program components execute in sequence on all processors. In parallel composition, different program components execute concurrently on different processors. In concurrent composition, different program components execute concurrently on the same processors.
The differences is that in sequential, a lot of program parts exist that help execute in stages on all given processors. While in parallel a lot of program parts execute concurrently on more than one processors.
What is the difference between parallel and sequential?Parallel computing is one where a given processes that is running do not wait for the former process to be done before it runs.
While Sequential is one where the process are said to be executed only by doing one at a time.
Therefore, the differences is that in sequential, a lot of program parts exist that help execute in stages on all given processors. While in parallel a lot of program parts execute concurrently on more than one processors.

Answers
Answer: D. Multiply the number of microseconds by 1,000.
Explanation:
In order to convert microseconds to nanoseconds, it should be noted that one should multiply the number of microseconds by 1,000.
For example, if we want to convert 12 microseconds to nanoseconds. This will be:
= 12 × 1000
= 12000 nanoseconds.
Therefore, with regards to the information given above, the correct option is D.

The simple main reason for this is that other languages are increasing in popularity. There are many open-source languages that are being optimized constantly and upgraded with new features. The ability for these languages to perform many tasks better than Java makes it the obvious choice when a developer is choosing a language to develop their program on. Two of these languages are Javascript and Python. Both can do everything that Java can and with less code, faster, and cleaner.

1. A company that produces office organizers is currently utilizing 10 hours per day to complete 90 pcs of the product. Engr Ulymarl, the senior process engineer proposes to do minor change in the process flow to avoid redundancy. By doing this, the output increased to 110 pcs. The material cost per organizer is BD 5; additional supplies needed to complete the organizer cost BD 1.50 and labor is paid at the rate of BD 2.5 per hour, energy cost is assumed to be BD 1.5 while water cost is at BD 1.75. a. Is there any improvement in productivity with the changes that have been implemented by the process engineer? b. Prove your answer though presenting the labor productivity, multifactor productivity and productivity improvement. c. What is your conclusion on the action done by Engr Ulymarl ?
Answers
a. Yes, there is an improvement in productivity as the output increased from 90 to 110 pcs.
b. Labor Productivity: 11 pcs/hour. Multifactor Productivity: 0.88 pcs/(BD 11.75) per day. Productivity Improvement: 22.2% increase.
c. Engr Ulymarl's action improved productivity by increasing output per hour and overall efficiency, leading to positive results and potentially better profitability.
a. Yes, there is an improvement in productivity with the changes implemented by the process engineer. The output increased from 90 to 110 pcs, indicating higher productivity.
b. To prove the improvement in productivity, we can calculate the following metrics:
Labor Productivity: Divide the output (110 pcs) by the labor hours (10 hours) to obtain the labor productivity per hour .Labor Productivity = Output / Labor Hours
Multifactor Productivity: Sum up the costs of materials, additional supplies, labor, energy, and water, and divide the output (110 pcs) by the total cost to calculate the multifactor productivity.Multifactor Productivity = Output / (Material Cost + Additional Supplies.
Cost + Labor Cost + Energy Cost + Water Cost)
Productivity Improvement: Compare the initial and improved productivity measures to determine the percentage increase.Productivity Improvement = ((Improved Productivity - Initial
roductivity) / Initial Productivity) * 100
c. Engr Ulymarl's action resulted in a significant improvement in productivity. The increased output per hour of labor indicates higher efficiency. The labor productivity, multifactor productivity, and productivity improvement calculations would provide concrete evidence of the positive impact of the process flow changes. The proposed actions by Engr Ulymarl have successfully enhanced productivity, leading to better output and potentially higher profitability for the company.

in css, a(n) selector defines the appearance of specific elements within other specific elements on the page, such as nav a.
Answers
The correct answer is Some of the popular selectors we looked at earlier can alternatively be described as attribute selectors, where an element is chosen based on its class or ID value.
To choose an element with a certain attribute or attribute value, use the CSS Attribute Selector. Grouping HTML components based on certain characteristics is a great approach to design them because the attribute selector will only choose elements with comparable properties. All elements with a specified attribute or an attribute set to a particular value are selected by an attribute selector. Like an illustration, the Selector is an unique kind of comparator that mediates data from two input sources based on a Boolean value, acting as a traffic light (equivalent to a single bit multiplexor). Open the Functions palette and choose the Programming palette to locate the Selector function.

To avoid mistyping because of the random cursor movement use the special function key to disable the touchpad when the laptop keyboard is used.
The built-in mouse pointer input device on a laptop is referred to as a touchpad. Touchpads are good for input from the mouse pointer and are entirely functional. The majority of individuals still prefer using a mouse over a touchpad to move their cursor, though.
However, you are unable to use your laptop's touchpad as an additional input device if a physical mouse is connected to it (there would simply be a clash between the two and the touchpad might also become a source of unintentional input). People frequently need to turn off their touchpads for this and a variety of other reasons.
