One of the key features of Go is its rich set of built-in data structures, which include <b>arrays</b>, <b>slices</b>, <b>maps</b>, <b>strings</b>, and <b>structs</b>. These data structures are essential for writing efficient and maintainable programs.
</p>
<p>
In this article, we'll explore each of these data structures in detail, including how to add, delete, and iterate through them, with practical examples.

<h3>
Arrays
</h3>
<p>
An array is a fixed-size collection of elements of the same type. The size of an array is part of its type, meaning you cannot resize an array once it is defined.
</p>
<h4>
Example:
</h4>

<pre style="font-size: 90%;">
<code class="language-go normalize-whitespace line-numbers" >
package main

import "fmt"

func main() {
    // Declare an array of 5 integers
    var numbers [5]int

    // Add elements to the array
    numbers[0] = 10
    numbers[1] = 20
    numbers[2] = 30
    numbers[3] = 40
    numbers[4] = 50

    // Print the array
    fmt.Println("Array:", numbers)

    // Iterate through the array
    for i := 0; i < len(numbers); i++ {
        fmt.Printf("Element at index %d: %d\n", i, numbers[i])
    }
}
</code>
</pre>

<h4>
Output:
</h4>
<pre style="font-size: 90%;">
<code class="language-text normalize-whitespace line-numbers" >
Array: [10 20 30 40 50]
Element at index 0: 10
Element at index 1: 20
Element at index 2: 30
Element at index 3: 40
Element at index 4: 50
</code>
</pre>

<h4>
Key Points:
</h4>
<ul style="margin-left: -15px">
<li>
Arrays have a fixed size.
</li>
<li>
Elements are accessed using indices.
</li>
<li>
Use a for loop to iterate through an array.
</li>
</ul>
