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.

[C++14]: Which of the following statements is false?
a. With the C++14 version of the equal algorithm to compare two sequences of values for equality, the second sequence must contain at least as many elements as the first—equal returns false if the sequences are not of the same length. b. With the C++14 version of the mismatch algorithm to compare two sequences of values, the algorithm returns a pair of iterators indicating the location in each sequence of the first mismatched elements. If all the elements match, the two iterators in the pair are equal to the end iterator for each sequence. c. Always use C++11’s versions of equal and mismatch – these are preferred because they compare the lengths of the ranges for you, eliminating a potential source of logic errors. d. In C++14, use = rather than braces when initializing a variable declared with auto.
