Question
**Problem Statement:**

Assume that the value of `p` is `0x7ffc0804`. What will be the value of `p + 3`?

**Code Snippet:**

```c
int values[5];
int* p = &values;
```

**Explanation:**

In the given code, `p` is a pointer to an array of integers. Assuming a 32-bit system where an `int` is 4 bytes, increasing a pointer by 3 will move it forward by `3 * 4 = 12` bytes.

**Calculation:**

Given `p = 0x7ffc0804`, the operation `p + 3` in hexadecimal is:

`0x7ffc0804 + 0x0000000C = 0x7ffc0810`.

So, the value of `p + 3` will be `0x7ffc0810`.

**Question:**

What is the return value of the code segment below?

```java
__________ getArray(int size)
{
    return new int[size];
}
```

In this code snippet, a method named `getArray` takes an integer parameter named `size`. The method returns a new integer array with the specified size. The missing return type for the method is `int[]`, indicating that the method returns an array of integers. 

**Explanation:**

To complete the method definition, it should look like this:

```java
int[] getArray(int size)
{
    return new int[size];
}
```

This code creates and returns a new array of integers, with each element initialized to zero by default. The size of the array is determined by the `size` parameter passed to the method.
