Program Plan Intro

To find:

Output of the given code segment.

Program Description Answer

b. Y

Explanation of Solution

In the given code in the first line, two int variables a and b have values as a = 3 and b = 4. Immediate next statement is If block statement.

If a statement is using equal to operator (==) to compare the value of both operands a and b .Equal to the operator will check if the operands on both sides of it are equal or not.

The operator will return false if operands are not equal and return true in case, they are equal.

Since a and b are not equal so if block will return false and hence the immediate next statement after it will not get executed.

The statement after the if block i.e. WriteLine("Y"); will get executed and hence the output will be Y.

3. Problem Description: Define the Circle2D class that contains: Two double data fields named x and y that specify the center of the circle with get methods. • A data field radius with a get method. • A no-arg constructor that creates a default circle with (0, 0) for (x, y) and 1 for radius. • A constructor that creates a circle with the specified x, y, and radius. • A method getArea() that returns the area of the circle. • A method getPerimeter() that returns the perimeter of the circle. • • • A method contains(double x, double y) that returns true if the specified point (x, y) is inside this circle. See Figure (a). A method contains(Circle2D circle) that returns true if the specified circle is inside this circle. See Figure (b). A method overlaps (Circle2D circle) that returns true if the specified circle overlaps with this circle. See the figure below. р O со (a) (b) (c)< Figure (a) A point is inside the circle.

1. Explain in detail with examples each of the following fundamental security design principles: economy of mechanism, fail-safe default, complete mediation, open design, separation of privilege, least privilege, least common mechanism, psychological acceptability, isolation, encapsulation, modularity, layering, and least astonishment.
Security in general means the protection of an asset. In the context of computer and network security, explore and explain what assets must be protected within an online university. What the threats are to the security of these assets, and what countermeasures are available to mitigate and protect the organization from such threats. For each of the assets you identify, assign an impact level (low, moderate, or high) for the loss of confidentiality, availability, and integrity. Justify your answers.
