Please kindly make sure that the output exactly matches the test case so I can vote a thumbs up. If it doesn't the program is wrong.
Test Cases and the given code are given after the prompt
Prompt:
Modify the given code to:
1.. Store the data in Binary file and access it in Random Access mode.
2.Replace Class with Structure for Employee and Department.
3. Inside each structure, replace all string variables with array of characters. please read the chapter 12(More about characters and strings). Though we do not have homework on this, the knowledge from this chapter will help you do the final exam project.
4. Make Employee and Department editable. That means, the user should be able to edit a given Employee and Department. Youc an allow the user to edit Employee name, age etc and assign him/her to different department. Similarly department name and department head can be changed. However, do not allow the uesr to Employee ID in Employee file and Department ID in department file.
5. Please note that the data will no longer be stored in the array as it was in the given code. Instead, it should be written to the file as soon as you collect the data from the user. If you are editing a record, read it from the file,collect new data from the user, store the record back to the file in the same place it was found inside the file. That means, the menu will not have options to save data to file or read data from file. Also, this should provide the ability for user to create unlimited number of employees and departments unlike in given code where you allowed only limited number of departments and employees.

The Gettysburg Address
President Abraham Lincoln
November 19, 1863
"Fourscore and seven years ago our fathers brought forth on this continent a new nation, conceived in liberty and dedicated to the proposition that all men are created equal.
Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and so dedicated, can long endure. We are met on a great battlefield of that war. We have come to dedicate a portion of that field as a final resting-place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this. But, in a larger sense, we cannot dedicate — we cannot consecrate — we cannot hallow — this ground. The brave men, living and dead, who struggled here have consecrated it, far above our poor power to add or detract. The world will little note, nor long remember what we say here, but it can never forget what they did here. It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us — that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion — that we here highly resolve that these dead shall not have died in vain — that this nation shall have a new birth of freedom and that government of the people, by the people, for the people, shall not perish from the earth."
Based on the document Gettysburg Address, what actions did enslaved people take during the Civil War and how were they treated by the Union army? How did the Emancipation Proclamation and the Gettysburg Address, change the purpose of the Civil War?

Chi-square tests are nonparametric tests that examine nominal categories as opposed to numerical values. Consider a situation in which you may want to transform numerical scores into categories. Provide a specific example of a situation in which categories are more informative than the actual values.
Suppose we had conducted an ANOVA, with individuals grouped by political affiliation (Republican, Democrat, and Other), and we were interested in how satisfied they were with the current administration. Satisfaction was measured on a scale of 1-10, so it was measured on a continuous scale. Explain what changes would be required so that you could analyze the hypothesis using a chi-square test. For instance, rather than looking at test scores as a range from 0 to 100, you could change the variable to low, medium, or high. What advantages and disadvantages do you see in using this approach? Which is the better option for this hypothesis, the parametric approach or nonparametric approach? Why?"

Consulting: INITIAL INTERVIEW
You are a CEO (Michelle Royal) of Goodwill Industries of Boston, which serves twelve locations in the greater Boston area. Overall, the stores are doing very well but you know they can be more successful and productive. For example, you have experienced positive retail revenue growth over the past three years; however, the growth was still lower than the average and your donor volume is down. On the other hand, your sales per square foot outperformed the national average.
Consequently, you called Headquarters (HQ) and investigated the possibility of having a consultant come to Boston to review your situation and give recommendations for improvement. You were talking to the CEO in Chicago and she explained that she found the consulting to be a very helpful exercise. The contact at HQ asked you a few questions and said that Jane/Joe Reynolds, an inhouse retail consultant, would be giving you a call.
You have been in your position for one year. You did not have any previous retail experience before taking the Goodwill position. You have pretty much continued the work of your predecessor and have tried to remain very independent and creative. For example, you and your staff like to create your own signage as opposed to using the standard Goodwill prototypes. Your expertise is finance and you have been able to implement and maintain excellent financial reports.
You suspect that improvement can be made through increased efficiency and production.
Some areas that you think might need attention: merchandise layout, pricing, sorting and processing, transportation. Furthermore, your new Retail Manager thinks one of your store managers might be ineffective. Your style has been rather formal. You tend to work one-on-one with your key managers and supervisors.
Though you want help (you really want to surpass all Goodwill averages), you are concerned about having a consultant come and "snoop around." You realize that this is the only way, however, so you decide to talk to the consultant and see what he suggests in terms of coming to Boston. You are very concerned about how he/she is going to go about the project. You would like to keep things very quiet, not involve too many people, and not stir things up. After all, it seems to you that things are going generally well.
Background info: The mission of Goodwill is to provide work for underprivileged and to do that through retail stores. The underprivileged are trained for a period of time by working in the stores and then sent out into the broader marketplace. Consequently, the Goodwill Stores (collecting old stuff and selling it), is only a means for the real mission.
Goodwill HQ has a team of internal consultants, each with different areas of expertise, who are available to travel to the different locations when they need help. The individual Goodwill locations are independent and are “loosely” tied to HQ, more as nonprofit associations, not industry. Consequently, the CEOs of the various Goodwill locations want assistance but also want to remain independent—the classic “push-pull” that consultants encounter.
Assignment:
You are the Goodwill HQ Consultant that Michelle calls. Since she is in Boston and you are in D.C., you decide to conduct the conversations (which you two have formally scheduled) through visual WEBX so you can see one another faces.
Brainstorm and jot down how you would go about the interview. Following the information in your consulting packet on how to conduct the exploratory phase of formulating an intervention, what questions would you ask? How would you explain your role and the parameters of the consulting arrangement? How would you gain Michelle’s trust? What kind of resistance do you think she will demonstrate? How will you handle that resistance?
Then, actually write out an entire conversation, making it up as you go, demonstrating the skills sets that you know you have to demonstrate. Have Michelle challenge you and deal with her resistance and getting through all phases of the exploratory phase. End the session by summarizing next steps.

Jenny had discovered some new friends on the Internet—friends who shared her interest in programming. One of these new friends sent her a link to a new warez (illegally copied software) site.
She downloaded a kit called Blendo from the warez site. Blendo is a tool that helps novice hackers create attack programs that combine a mass e-mailer with a worm, a macro virus, and a network scanner. She clicked her way through the configuration options, clicked a button labeled “custom scripts,” and pasted in a script that one of her new friends had e-mailed to her. This script was built to exploit a brand-new vulnerability (announced only a few hours before).
Although she didn’t know it, the anonymous high-schooler had created new malware that was soon to bring large segments of the Internet to a standstill.
She exported the attack script, attached it to an e-mail, and sent it to an anonymous remailer service to be forwarded to as many e-mail accounts as possible. She had naively set up a mailback option to an anonymous e-mail account so she could track the progress of her creation. Thirty minutes later, she checked that anonymous e-mail account and saw that she had more than 800,000 new messages; the only reason there were not even more messages was that her mailbox was full.

In 1943 Abraham Maslow proposed that individuals have five basic needs, arranged in a hierarchy from lowest to highest they are physiological, safety, love, esteem, and self-actualization. David McClelland focused on a needs-based theory which proposed that individuals have three basic needs: the need for achievement, the need for affiliation, and the need for power. The needs described in both these theories are often used by managers during the motivation and goal-setting process with employees.
