# 1. Introduction

Sorting is a common operation in programming when you want to order elements in a list. In Go, sorting an array or a slice is straightforward, thanks to the sort package in the standard library. This post will show how to sort an array of integers in Go using the sort package.

## Definition

Sorting in Go involves reordering the elements of an array (or a slice) so that they meet a specific condition, usually either in ascending or descending order. The sort package contains functions like sort.Ints and sort.Sort to sort slices of basic types and user-defined types, respectively.

# 2. Program Steps

1. Create an array (or slice) of integers.

2. Convert the array to a slice if you're working with an array.

3. Use the sort.Ints function to sort the slice.

4. Print the sorted slice to verify the results.

# 3. Code Program

``````package main

import (
"fmt"
"sort"
)

func main() {
// Step 1: Create a slice of integers (Go's sort functions require a slice, not an array)
numbers := []int{7, 2, 4, 8, 1, 3}

// Step 2: Use sort.Ints to sort the slice
sort.Ints(numbers)

// Step 3: Print the sorted slice
fmt.Println("Sorted numbers:", numbers)
}

``````

### Output:

```Sorted numbers: [1 2 3 4 7 8]
```

### Explanation:

1. package main - Defines the main package.

2. import "fmt" and import "sort" - Import the necessary packages for formatting and sorting functionality.

3. numbers is a slice of integers that needs to be sorted.

4. sort.Ints(numbers) - Calls the sort.Ints function from the sort package, which sorts the slice of integers in-place in ascending order.

5. fmt.Println - Prints the sorted slice.

6. The output shows the numbers sorted in ascending order.

7. Note that while the example uses a slice (as Go's sort functions require slices), if you have an array, you can convert it to a slice with myArray[:] and then sort it.
