Explain the purpose and use of the AND operator.

What will be an ideal response?

Most programming languages allow you to ask two or more questions in a single comparison by using a conditional AND operator, or more simply, an AND operator that joins decisions in a single statement. For example, if you want to bill an extra amount to cell phone customers who make more than 100 calls that total more than 500 minutes in a billing period, you can use nested decisions, or you can include both decisions in a single statement by writing the following question:

callsMade > CALLS AND callMinutes > MINUTES?

When you use one or more AND operators to combine two or more Boolean expressions, each Boolean expression must be true for the entire expression to be evaluated as true. For example, if you ask, "Are you a native-born U.S. citizen and are you at least 35 years old?", the answer to both parts of the question must be "yes" before the response can be a single, summarizing "yes." If either part of the expression is false, then the entire expression is false.

Which of the following statements is true?

a) The C standard library does not provide a secure random-number generator. b) According to the C standard document’s description of function rand, “There are no guarantees as to the quality of the random se-quence produced and some implementations are known to produce sequences with distressingly non-random low-order bits.” c) The CERT guideline MSC30-C indicates that implementa-tion-specific random-number generation functions must be used to ensure that the random numbers produced are not predictable d) All of the above.
