Rust | Array Example: Write a program to add two integer arrays.
Submitted by Nidhi, on October 22, 2021

Problem Solution:

In this program, we will create two arrays of integer elements then we will add both arrays and print the result.

Program/Source Code:

The source code to add two integer arrays is given below. The given program is compiled and executed successfully.

```// Rust program to add two arrays

fn main()
{
let mut arr1:[usize;5] = [0,1,2,3,4];
let mut arr2:[usize;5] = [5,6,7,8,9];
let mut arr3:[usize;5] = [0;5];

let mut i:usize=0;

while i <= 4
{
arr3[i] = arr1[i] + arr2[i];
i = i + 1;
}

println!("arr1     : {:?}",arr1);
println!("arr2     : {:?}",arr2);
println!("arr1+arr2: {:?}",arr3);
}
```

Output:

```arr1     : [0, 1, 2, 3, 4]
arr2     : [5, 6, 7, 8, 9]
arr1+arr2: [5, 7, 9, 11, 13]
```

Explanation:

Here, we created two arrays of integers with 5 elements and then we added both arrays and printed the addition of array elements.
