# Rust program to create a closure function to check given number is EVEN or ODD

Rust | Iterator and Closure Example: Write a program to create a closure function to check given number is EVEN or ODD.
Submitted by Nidhi, on November 22, 2021

Problem Solution:

In this program, we will create a closure function to check a given number is EVEN or ODD and print the appropriate message.

Program/Source Code:

The source code to create a closure function to check the given number is EVEN or ODD is given below. The given program is compiled and executed on UBUNTU 18.04 successfully.

```// Rust program to create a closure function
// to check given number is EVEN or ODD

fn main()
{
let num1 = 10;
let num2 = 21;

let check_even = |n|
{
if n%2==0
{
println!("EVEN");
}
else
{
println!("ODD");
}
};

check_even(num1);
check_even(num2);
}
```

Output:

```EVEN
ODD
```

Explanation:

Here, we created two integer variables num1, num2 initialized with 10, 21 respectively. Then we created a closure function check_even with parameter "n". In the closure, we checked the given number is an EVEN or ODD and printed the appropriate message
