[C++11]: To help prevent errors, apply C++11's ________ keyword to the prototype of every derived-class function that overrides a base-class virtual function.

5 / 5 pts The new C++14 stream manipulator ________ enables a program to read quoted text from a stream, including any white space characters in the quoted text, and discards the double quote delimiters. For example, if we read 100 "Janie Jones" 24.98 using inClientFile>> account>> quoted(name)>> balance; the first stream extraction reads 100 into the int variable account, the second reads Janie Jones as one string and stores it in the string variable name without the double-quote delimiters, and the third stream extraction reads 24.98 into the double variable balance.

quoted

The istream member function _______ is normally used when reading data from a file in random-access applications.

read

A self- ___________ class is used to form dynamic data structures that can grow and shrink at execution time

referential

Suppose you have a shopping list stored in a vector. What function would you use to remove all items in that vector that are under 10 dollars and place them in another container?

remove_copy_if

Which function changes the actual string stored in the string object (i.e., is not a const member function)?

resize

s1.compare(0, 3, s2, 0, 3);

If string s1 has the value "computer" and string s2 has the value "promise", which call to insert will produce the string "compromise"?

The process of determining if an array contains a particular key value is called ______________ the array.

searching

The __________ function would produce the sequence 1, 5, 6 when passed the sequences 1, 2, 3, 4, 5, 6 and 2, 3, 4, 7 as first/second and third/fourth arguments, respectively.

set_difference

The __________ function would produce a sequence containing three elements when passed the sequences 1, 2 and 1, 2, 3, 4, 5 as first/second and third/fourth arguments, respectively.

set_symmetric_difference

As of C++11, you can ask a vector or deque to return unneeded memory to the system by calling member function shrink_to_fit. This requests that the container reduce its capacity to the number of elements in the container. According to the C++ standard, implementations can ignore this request so that they can perform implementation-specific optimizations.
