Self Assesment Questions 22

Instructions

For each question choose the single response which best answers the question, or which completes the statement most accurately.

Topic 22: The Standard Template Library

Question 184:

The string class encapsulates:

the data and functions of an inbuilt char* string

only the data of an inbuilt char* string

only the functions of an inbuilt char* string

the data and functions of a sequence of char*'s

None of the above.

Question 185:

Suppose the string s holds the characters "examination". What will s hold after the following statement: s.replace(2,1,"ter")

"exaternation"

"examinater"

"extermination"

"teramination"

"termination"

Question 186:

If s is a string holding the character "a", what is the effect of the statement: s += 2;

s holds "a2"

s holds "a\002"

s holds "aaa"

It's a compiler error

It's a run-time error

Question 187:

Name of the deque class comes from:

the acronym "Double Ended QUEue"

the acronym "Dynamically Extended QUEue"

the acronym "Discrete Elements, Quantised Under Extension"

the name of woman who invented it: Marie Alperìn de Qué

the initials of the French ISO sub-committee ("Domaine Elévè Qui Utilisant les Extensiones") which proposed its inclusion in the Standard Template Library.

Question 188:

The deque and list classes are both optimized for:

insertion at the end of the sequence.

insertion at the start of the sequence.

insertion in the middle of a sequence.

insertion at either end of a sequence.

completely different things.

Question 189:

The member function push_back() has what effect on a list, vector or deque object?

It creates a new slot at the end of the container (the slot is uninitialized)

It pushes a value back onto the start of the container.

It pushes a value back onto the end of a container.

It pushes a value back off the end of a container.

It undoes the last deletion of an element in the container.

Question 190:

The type name map<int,string> produces a type with essentially the same characteristics and abilities as:

list<string>

map<int,char*>

map<string,int>

vector<int>

vector<string>

Question 191:

The complex class template may only be given certain types as its template parameters:

int, float, or double

int, long, or double

int, float, or char*

int, double, or long double

float, double, or long double

Question 192:

The <complex> header file also declare overloaded an overloaded versions of which of the following functions:

qsort()

exp()

trunc()

fact()

All of the above.
