Operator precedence in java: The C++ has well-defined set of rules that specifies the order in which the operators in an expression gets evaluated. For example, in C++ it is defined that the multiplication and division has higher precedence than subtraction or addition. The operations multiplication, division and modulus have same precedence. The operations addition, subtraction and modulus have same precedence. The operators , / and % are higher precedence than operators + and -. In C++, the parenthesis gets more priority than any other operator. Example for evaluation of expression with parenthesis: Consider the below expression, 4(2(3+2)) In the above expression, the innermost parenthesis gets evaluated first. That is (3+2) is evaluated and it results 5. Then this 5 is multiplied using 2 and the result is 10. Then 10 are multiplied with 4 and the result is 40. Example for evaluation of expression without parenthesis: Consider the below expression, 423+2 If there is no parenthesis, the result of this expression will be 26. This is found according to the operator precedence. The operator () has higher precedence than “+”. If an expression contain more than one operator with same precedence, their associatively defines the order of evaluation. Then the evaluation does either using left-to-right or right-to-left order.

Program Plan Intro

Operator precedence in java:

The C++ has well-defined set of rules that specifies the order in which the operators in an expression gets evaluated.

For example, in C++ it is defined that the multiplication and division has higher precedence than subtraction or addition.

The operations multiplication, division and modulus have same precedence.

The operations addition, subtraction and modulus have same precedence.

The operators , / and % are higher precedence than operators + and -.

In C++, the parenthesis gets more priority than any other operator.

Example for evaluation of expression with parenthesis:

Consider the below expression,

4(2(3+2))

In the above expression, the innermost parenthesis gets evaluated first. That is (3+2) is evaluated and it results 5. Then this 5 is multiplied using 2 and the result is 10. Then 10 are multiplied with 4 and the result is 40.

Example for evaluation of expression without parenthesis:

Consider the below expression,

423+2

If there is no parenthesis, the result of this expression will be 26. This is found according to the operator precedence. The operator () has higher precedence than “+”.

If an expression contain more than one operator with same precedence, their associatively defines the order of evaluation. Then the evaluation does either using left-to-right or right-to-left order.

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.
