Final Exam Review

A function __________ eliminates the need to place a function definition before all calls to
the function.

The value in a(n) _______ variable persists between function calls.

This is a collection of statements that performs a specific task.

A function can have zero to many parameters, and it can return this many values.

This statement causes a function to end.

Look at the following function prototype.

int myFunction(double, double, double);

How many parameter variables does this function have?

Which line in the following program contains the header for the showDub function?

1 #include
2 using namespace std;
3
4 void showDub(int);
5
6 int main()
7 {
8 int x = 2;
9
10 showDub(x);
11 cout << x << endl; 12 return 0; 13 } 14 15 void showDub(int num) 16 { 17 cout << (num * 2) << endl; 18 }

In a function header, you must furnish

A(n) _________ is information that is passed to a function, and a(n) _________ is
information that is received by a function.

True/False: A function’s return data type must be the same as the function’s parameter(s).

True/False: Assume array1 and array2 are the names of arrays. To assign the contents
of array2 to array1, you would use the following statement.

array1 = array2;

A two-dimensional array of characters can contain

True/False: Each individual element of an array can be accessed by the array name and an
element number, called a subscript.

To pass an array as an argument to a function, pass the _________ of the array.

A two-dimensional array can be viewed as ___________ and _____________.

This vector function returns true if the vector has no elements.

This vector function returns the number of elements in a vector.

What does the following statement do?

vector v(10, 2);

An array can easily be stepped through by using a

True/False: The statement

double money[25.00];

is a valid C++ array definition.

When an array is sorted from highest to lowest, it is said to be in _____ order.

The _________ sort usually performs fewer exchanges than the ________ sort.

True/False: Before you can perform a bubble sort, the data must be stored in descending
order.

A ________ algorithm is a method of locating a specific item of information in a larger
collection of data.

True/False: A linear search can only be implemented with integer values.

Using a linear search to find a value that is stored in the last element of an array of 20,000
elements, ____________ element(s) must be compared.

Data that is sorted in ascending order is ordered

__________ algorithms are used to arrange random data into some order.

True/False: The number of comparisons made by a binary search is expressed in powers of
two.

A(n) ________ search is more efficient than a(n) ________ search

What is the output of the following program?

#include
using namespace std;

void showDub(int);

int main()
{
int x = 2;

showDub(x);
cout << x << endl; return 0; } void showDub(int num) { cout << (num * 2) << endl; }

Here is the header for a function named computeValue:

void computeValue(int value)

Which of the following is a valid call to the function?

True/False: A static variable that is defined within a function is initialized only once, the first time the
function is called.

This function causes a program to terminate, regardless of which function or control
mechanism is executing.

These types of arguments are passed to parameters automatically if no argument is provided
in the function call.

If a function is called more than once in a program, the values stored in the function’s local
variables do not _________ between function calls.

Unlike regular variables, these can hold multiple values.

What will the following code display?

int numbers[] = {99, 87, 66, 55, 101 };
cout << numbers[3] << endl;

An array of string objects that will hold 5 names would be declared using which statement?

When writing functions that accept multi-dimensional arrays as arguments,
_______________ must be explicitly stated in the parameter list.

Arrays may be ___________ at the time they are __________.

The name of an array stores the __________ of the first array element.

True/False: You must furnish an argument with a function call.

True/False: Local variables are initialized to zero by default.

If a function does not have a prototype, default arguments may be specified in the function
___________.

What is the output for the following code?

#include
using namespace std;

void doSomething(int&);

int main()
{
int x = 2;

cout << x << endl; doSomething(x); cout << x << endl; return 0; } void doSomething(int& num) { num = 0; cout << num << endl; }

True/False:
A parameter is a special-purpose variable that is declared inside the parentheses of a
function definition.

True/False: An individual array element can be processed like any other type of C++
variable.

The ______________ is automatically appended to a character array when it is initialized
with a string constant

Which statement correctly defines a vector object for holding integers?
