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;

Function.

A ________ variable is declared outside all functions.

Global.

A ______ can be used to specify the starting values of an array.

Initialization list.

Arrays may be ________ at the time they are _________.

Initialized; declared.

(Going to give us an assignment statement which incorporates a logical comparison. We have to say what the final variable that is assigned to the statement is). (Remember: 1 means it's true, 0 if false).

N/A

(Going to give us an if-then-else chain and tell us what the person has input as a value. We have to say what it will print out).

N/A

(Will give us an array element definition and we need to say what will be the last legal subscript). (remember: starts at zero and doesn't go past the size declarator.)

N/A

Given the following declaration, which element has a particular value

N/A

How many elements does the following array have: _____________

N/A

Is this array illegal or not?

N/A

Which of the following is a valid C++ array example.

N/A

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

Name.

Need to know the rules governing array definitions (size declarator, brackets, names and datatype)

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

Null terminator.

A two dimensional array can have elements of _______ datatype.

One.

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

Only one.

The due while loop is a ______ loop that is ideal in situations where you always want the loop to iterate at least once.

Post-test loop

A function _______ eliminates the need to put a function definition before all calls to the function.

Prototype.

When used as parameters, these types of variables allow a function to access the parameter's original argument.

Reference.

This statement causes a function to end.

Return.

A 2D array can be viewed as _____ and _____.

Rows; columns.

To access an array element, use the array name and the element's _______.

The break expression.

An array can store a group of values, but the values must be:

The same datatype.

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

True.

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

True.

Global variables are initialized to zero by default.

True.

IT is possible for a function to have some parameters with the fault arguments and some without

True.

It is not considered good programming practice to declare all of your variables globally.

True.

One reason for using functions is to break programs into manageable units or modules.

True.

The amount of memory used by an array depends upon the arrays datatype and the number of elements in the array.

True.

The parameter is a special purpose variable that is declared inside the parenthesis of a function definition.

True.

When you pass an array as an argument to a function, the function can modify the contents of the array.

True.

You may use the exit() function to terminate a program, regardless of which control mechanism is executing

True.

_______ functions may have the same name as long as their parameter lists are different.

In a function header you must furnish ________.

(All of these).

This operator is used in C++ to represent equality.

==

Which of the following statements about global variables is true.

A global variable can have the same name as a variable that is declared local within a function.

Unlike regular variables these can hold multiple values.

Arrays.

A function is executed when it is _______.

Called.

A function's return datatype must be the same as the functions parameters
