Last Updated : October 09, 2021

Problem Statement

In this program, we will create a user-defined function to return the array to the calling function.

Program/Source Code

The source code to return an array from the function is given below. The given program is compiled and executed successfully.

// Rust program to return an array 
// from the function

fn GetArray()->[i32;5] {
    let mut arr:[i32;5] = [10,20,30,40,50];
    
    return arr;
}

fn main() {

   let arr = GetArray();
   println!("Array Elements: ");
	for i in 0..5 {
		println!("{0} ", arr[i]);
	}
}

Output

Array Elements: 
10 
20 
30 
40 
50

Explanation

In the above program, we created two functions GetArray() and main(). The GetArray() function is a user-defined function that returns the array to the calling function.

In the main() function, we called GetArray() function to get the array of integers. Then we printed the returned array.
