# Rust program to swap adjacent elements of the array

Rust | Array Sorting: Write a program to swap adjacent elements of the array.
Submitted by Nidhi, on October 22, 2021

Problem Solution:

In this program, we will create an array of integers then we will swap the adjacent elements of the array and print the updated array.

Program/Source Code:

The source code to swap adjacent elements of the array is given below. The given program is compiled and executed successfully.

```// Rust program to swap adjacent elements
// of the array

fn main()
{
let mut arr:[usize;6] = [0,1,2,3,4,5];
let mut i:usize=0;
let mut temp:usize=0;

println!("Array before swapping: {:?}",arr);

while i<=4
{
temp = arr[i];
arr[i] = arr[i+1];
arr[i+1] = temp;
i = i + 2;
}

println!("Array after swapping: {:?}",arr);
}
```

Output:

```Array before swapping: [0, 1, 2, 3, 4, 5]
Array after swapping: [1, 0, 3, 2, 5, 4]
```

Explanation:

Here, we created an array of integers with 6 elements, and then we swapped the adjacent elements of the array. After that, we printed the updated array.
