### Understanding Basic Loops in Visual Basic
This example demonstrates a simple Visual Basic program designed to read five numbers, calculate their sum and average, and then display each number along with its difference from the average.
```vb
Module Module1
Sub Main()
Dim Size As Integer = 5
Dim Sum As Double = 0
Dim Average As Double = 0
Dim TheNumbers(Size) As Double
Console.WriteLine("Input 5 numbers total")
For index = 0 To 4 Step 1
Console.WriteLine("Enter a number")
TheNumbers(index) = Console.ReadLine()
Sum = Sum + TheNumbers(index)
Next
Average = Sum / Size
For index = 0 To 4
Console.WriteLine("The number is " & TheNumbers(index))
Console.WriteLine("The difference from the average is " & TheNumbers(index) - Average)
Next
End Sub
End Module
```
#### Program Explanation
- **Variables:**
- `Size`: Specifies the total number of inputs, set to 5.
- `Sum`: Used to store the cumulative sum of the numbers entered.
- `Average`: Stores the average of the entered numbers.
- `TheNumbers`: An array holding the inputted numbers.
- **Flow of the Program:**
1. **Input Phase:**
- The program prompts the user to input five numbers.
- It reads each number and adds it to `Sum`.
2. **Calculating Average:**
- Once all numbers are inputted, it calculates the average by dividing `Sum` by `Size`.
3. **Output Phase:**
- The program iterates through the array to print each number and its difference from the average.
This program provides a basic understanding of loops and arrays in Visual Basic, important for handling repetitive tasks and data storage.
