**Program Explanation for Finding Differences Between Consecutive Elements in an Array**

In this educational module, we will guide you through creating a program that performs the following tasks:

1. **Prompts the user to enter an integer representing the size of an array of integers.**
2. **Fills the array with integers from the user input.**
3. **Creates an array of integers to hold the differences between two consecutive elements and displays it accordingly.**

### Example:
For illustration, consider an example where the array is of size 7 filled using values entered by the user. 

The array of differences contains:
- `-10` which is `(22 - 32)`,
- `2` which is `(32 - 30)`,
- `-18` which is `(30 - 48)`,
- and so forth.

Here is a sample run of the program for clarity:

**Sample run:**

- **Enter the size of the array:** `7`
- **Enter 7 integers:** `22 32 30 48 54 26 21`
- **Differences:** `-10 2 -18 6 28 -5`

The program takes the user input as follows:
1. The size of the array (which is `7` in this example).
2. Then, it takes `7` integer values input by the user to fill the array: `22, 32, 30, 48, 54, 26, 21`.
3. Finally, it computes the differences between each pair of consecutive elements and displays an array of these differences.

### Explanation of Differences:
- The difference between the 1st and 2nd elements: `22 - 32 = -10`.
- The difference between the 2nd and 3rd elements: `32 - 30 = 2`.
- The difference between the 3rd and 4th elements: `30 - 48 = -18`.
- The difference between the 4th and 5th elements: `48 - 54 = -6`.
- The difference between the 5th and 6th elements: `54 - 26 = 28`.
- The difference between the 6th and 7th elements: `26 - 21 = 5`.

By following these steps, you can create a program that efficiently calculates and displays the differences between consecutive elements in an array.
