Write a C++ program where class 1 and class 2 (which is a base class) should have a derived class (class 4 and class 5). Each of the derived classes should include at least 1 variable, 2 functions (one will be showing the function overriding case, the second one will be showing the function overloading case), 2 constructors (with default values, with parameters).

Then class 3 (composition) (to relate class 1 and class 2) should include 3 variables (first variable is an object belongs to class 1, second variable is an object belongs to class 2,third variable is class 3 own variable), 3 functions.

Write a program to calculate the amount of money in an account:

The user will input initial deposit and the number of years to leave that money in the account.

The interest is constant at 0.5% for the entire length of time.

The output will be the balance, with interest compounded annually.

(simple interest formula: interest = principal * rate)

Find an article from the internet about Computer security and then write a summary of that article. Include why you were interested in the article, what you learned from it, and how you could use it in your career as a cyber security professional. (minimum 1300 words)

The following methods are used: main(...), the encode(...) and the decode()....Is there any issue with one of the method? If yes can you correct it.

You are requested to implement the same program without the two methods encode() and decode()...

Implement the code only with the main() and test your program again.

During the systems development life cycle (SDLC), certain key problems discovered in the later stages could be directly traced back to inadequate and/or poor efforts in the requirements phase and industry studies show that over 50% of systems problems belong to this case. In addition, as mentioned in this week lecture notes "the cost of errors in requirements that weren’t discovered until later" may go up to 1,000 times. As a systems analyst, what should we do to minimize this problem? How might this be avoided?

Please no handwritten notes as those are hard to read.

Write a pseudo code program for a goal-based agent. The goal of the agent is to find the exit of a labyrinth.

• The agent is not omniscient
• The agent can sense if it is next to a wall (in front, left or right)
• The agent can turn 90 degrees to the right or left
• The agent can drive 1unit forward

The maze is constructed of paths that are 1 unit across (wide)

Show a maze of your choosing and illustrate the path taken from start to exit according to your program (example shown here).

In the fall 0f 2008 Countrywide Morgage Corporation announced that the private information for thousands of their customers, including social security numbers and loan numbers, had been compromised. Countrywide offered these customers a free 2-year subscription to a credit protection service. Should this action shield Countrywide from customer lawsuits? Could Countrywide do more? Should they? Given that it was a Countrywide employee who sold the data, does this change Countrywide's responsibilities toward the affected customers? Explain why or why not.
