Submitted by Nidhi, on October 20, 2021

Problem Solution:

In this program, we will create an integer array with 5 elements then we will calculate the sum of array elements.

Program/Source Code:

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

// Rust program to calculate the sum 
// of array elements

fn main() {
   let arr:[i32;5] = [1,2,3,4,5];
   let mut sum:i32 = 0;
   let mut i:usize = 0;
   
   while i<arr.len()
   {
	sum = sum + arr[i];	
	i = i + 1;
   }
   println!("Sum of array elements is: {}", sum);
}

Output:

Sum of array elements is: 15

Explanation:

Here, we created an array of the integer with 5 elements. Then we calculated the sum of array elements and stored the result into variable sum. After that, we printed the result.
