Rust program to add two integer arrays

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;
    
    // Add two arrays
    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.
