## Overview
We can use the `~` (tilde) operator to join or concatenate two arrays.
## Syntax
```D
array1 ~ array2
```
## Parameters
- **`array1`**: The first array.

- **`array2`**: The second array.

## Return value
The value returned is a concatenation of `array1` and `array2`.

## Example
Let's look at the code below:


// import stdio
import std.stdio;

// main method
void main () { 
   // an array with 5 elements. 
   double[5] a = 5; 
   double[5] b = [1, 2, 3, 4, 5]; 
   double [] c; 
   c = a~b; 
   writeln("Array c: ",c);
} 

# Explanation
* **Line 2**: We import the `std.stdio` for input and output operations.
* **Line 5**: We create the main method.
* **Lines 7 and 8**: We create` a` and `b` arrays.
* **Line 9**: We create an empty array that holds the concatenation of arrays `a` and `b` using the `~` operator.
* **Line 11**: We print the values of the array.
