Write a program that reads a file consisting of students’ test scores in the range 0-200. It should then determine the number of students having scores in each of the following ranges: 0-24, 25-49, 50-74, 75-99, 100-124, 125-149, 150-174 and 175-200. Use labels to display the score ranges and the number of students for each range. The data file, testscores.txt,
: You must use an array to hold the scores that are read from the file.
Extra :
Add a check box to the form. When the checkbox is selected, the program should display on the form the class average.

Create a class called Rectangle to represent a rectangle. The class should contain:
· Two fields named width and height.
· A constructor that creates a rectangle with the specified width and height. The default values are 1 and 2 for width and height, respectively.
· The accessor and mutator methods for width and height.
· A method named getArea() that returns the area of the rectangle.
· A method named getPerimeter() that returns the perimeter of the rectangle.
Once you have completed the class, write a program to test it. Be sure to test all methods in the class as well as test the default settings.

domestic or international conflict that is cyber-related
Research a current domestic or international conflict in the cyber domain.
As a way of checking for your understanding of the nature of conflict as described in the video,write a 1-page methodology for resolving the conflict using Microsoft® Word that addresses the following:
- Identify the reason for the conflict and the opposing forces
- Accurately identify the key political figures that impact the outcome or resolution of the conflict
- If you were involved with the resolution of the conflict, what style of conflict resolution would you use–the competing shark, the collaborating owl, the avoiding turtle, the accommodating teddy bear, or the compromising fox–and why?
- Do you think in our current political environment we may take the easy way out and try to sweep the conflict under the rug?
- There is one simple widely used method to resolve common conflict that goes by the acronym DESC that stands for Describe, Express, Specify, Consequences. Do you think this method could be used to resolve the conflict you identified? Do you think methods for conflict resolution in the workplace are the same as geological conflicts? Why or why not?

geopolitics of key nations (include at a minimum: U.S., China, Russia, Israel, and Iran)
Create a 1-page 4 row by 3 column table in Microsoft® Word that depicts laws for the U.S. and two other key nations in the strategic, tactical, and operational areas of cybersecurity. Provide a brief description of the law for each category of cybersecurity provided. The table column headings could be U.S., Russia, and China, for instance (or two other key nations of your choice). The row labels are Strategical, Tactical, and Operational.
Create a Microsoft® PowerPoint® presentation containing 8 slides, including Introduction, Conclusion, and Reference slides. Include detailed speaker notes with each slide.
Scenario: You are attending the company board meeting with your supervisor, the VP of Information Technology. The U.S.-based company is considering expanding into 100 countries worldwide. You will be presenting to the Board of Directors so they can understand the cyber threat each key nation poses to the company so they can make a more informed decision on how best to achieve international growth. Your task is to:
- Accurately define “geopolitics”
- Identify the geopolitics of key nations (include at a minimum: U.S., China, Russia, Israel, and Iran)
- Accurately describe the differences of each key nation’s political stance on cyber war
- Describe past international cyber conflicts and the resulting impact to the economy of each nation involved
- Accurately define “cyber-attack”
- State the impact of cyber-attacks on U.S. companies

Show all your work.
Score: 40 pts
Exercise I (2*15 = 30)
There are three processes in the scheduling queue and assume that all three of them are ready to run. Assume that P1 arrived a little before P2; and P2 arrived a little before P3. Scheduling starts at time t = 0. The CPU and I/O burst patterns of the three processes are as shown below:
Given the following processes that arrived in the order shown
| CPU Burst Time | IO Burst Time | CPU Burst Time | IO Burst Time | CPU Burst Time | |
| P1 | 4 | 2 | 4 | 2 | 4 |
| P2 | 5 | 2 | 5 | ||
| P3 | 2 | 2 | 2 | 2 | 2 |
Each process exits the system once its CPU and I/O bursts as shown above are complete.
Show the activity in the processor and the I/O area using the FCFS, SJF, and Round Robin (time quantum = 2) algorithms
For each algorithm, compute the average waiting time, the average response time, and the throughput.
Exercise II (Time scale as shown in class = 5pts, Table below = 5pts)
Recall that Shortest Remaining Job First (SRJF) is a variant of Shortest Job First (SJF) with preemption added in. Consider the following three processes vying for the CPU. The scheduler uses SRJF. The scheduler re-evaluates which process to run only upon the arrival of a new process into the scheduling queue, or the completion of a process. The table shows the arrival time of each process.
| Process | Arrival Time | Execution Time |
| P1 | To | 5 ms |
| P2 | To + 2 ms | 4 ms |
| P3 | To + 3 ms | 1 ms |
The scheduling starts at time To.
Fill in the table below with the process that is executing on the processor during each time slot. Be sure to show your work as to how you arrived at schedule.
| To+ | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |

network engineering
You work as the senior network engineer for a medium size organization. The company has offices in Miami and Los Angeles. The network as now has connectivity between locations. Many interoffice phone calls are placed between locations each day, and the organization realizes that it is spending a very large sum on a monthly basis for communication. Your boss approaches you. He wants you to research a solution that will eliminate the toll charges to the company and still allow for data communication across the wide area network (WAN).
Research a solution and explain your findings in a 2-3-page document. Utilizing the online library, the Internet, and all course materials, complete the following:
Explain to your manager how the solution you have identified will be implemented.
List the benefits of the solution.
Ensure that this solution will eliminate all interoffice toll charges.
The design and the implemented solution should not adversely affect the network performance across the WAN.
Diagram your proposed network layout.

Role of Data Mining
Search for a relevant and/or timely article involving data mining. Describe the role of “data mining” in the story using your own words. Try to identify the type of data analysis method used (association, classification, cluster, outlier, etc.). (100 word minimum – 300 word max). Include the link to the article.
Here is an example:
Posting Title: IBM, Mayo Clinic Take Next Data Mining Step
This story describes how Mayo clinic uses knowledge discovery tools to analyze the data on its patients in order to develop individualized care. For example, a doctor treating a patient for cancer could use data mining to find the results of treatments given to the similar patients and use this information to find the best treatment course for new patient.
Based on what I read in the textbook, I believe this is an example of classification since data mining is used to predict the best treatment based on past “training” data.
I can see how this can apply to medical treatments worldwide and have a positive long-term effect on medical delivery. As someone whose family member has cancer, I am hoping that data mining will help find a cure for her.

codes for a function that receives two parameters
There are two parts.
1. Write code for a function that receives two parameters (a,and b) by value and has two more parameters (c and d) by reference. All parameters are double.
The function works by assigning c to (a/b) and assigning d to (a*b).
From main, use scanf to get two numbers, then call the function, and then display both returned values to the output in a printf statement.
2. After part 1 is completed, write code to get 20 integer numbers from the user. The code then displays how many of those numbers are above the numbers average. To get proper credit you must follow these steps:
a. write a for loop to fill the array with numbers from the user. Use a pointer
b. use an index to pass through all array elements to calculate the average in another loop.
c. write a function, then pass the array, its size, and the average to the function. The function returns the count of the number of elements that are above the average.
