A pointer variable is the variable that can store the address of a variable? 

A pointer variable is the variable that can store the address of a variable?

The address operator(`&`) is used to get the value of a variable.

The address operator(<code>&amp;</code>) is used to get the value of a variable.

A pointer variable can't point to other pointer variables.

A pointer variable can’t point to other pointer variables.

Which of the following statements initializes the pointer to the address of the `x` variable?

Which of the following statements initializes the pointer to the address of the <code>x</code> variable?

```cpp

What is the index number of the last element of an array with 27 elements?

What is the index number of the last element of an array with 27 elements?

Which of the following declares an array of int named arr?

Which of the following declares an array of int named arr?

What is the output of the following code fragment:
```cpp
int ar[] = {2, 4, 6, 8 };

ar[0] = 23;
ar[3] = ar[1];

cout << ar[0]<< "and" <<ar[3] << endl;
```

What is the output of the following code fragment:
<pre><code class="language-cpp">int ar[] = {2, 4, 6, 8 };

ar[0] = 23;
ar[3] = ar[1];

cout &lt;&lt; ar[0]&lt;&lt; &quot;and&quot; &lt;&lt;ar[3] &lt;&lt; endl;
</code></pre>

The program is defective and will not compile.

What is the output of the following code fragment:

```cpp
int* z = new int[9];

z[0] = 7;
z[1] = 3;
z[2] = 4;

cout<< z[0]+z[1] << "and" << z[5] << endl;
```

What is the output of the following code fragment:
<pre><code class="language-cpp">int* z = new int[9];

z[0] = 7;
z[1] = 3;
z[2] = 4;

cout&lt;&lt; z[0]+z[1] &lt;&lt; &quot;and&quot; &lt;&lt; z[5] &lt;&lt; endl;
</code></pre>
