+Control flow is a fundamental concept in any programming language, including Rust. The `if-else` statement is a basic control flow construct that allows you to execute different code blocks based on certain conditions.
+
+## Your task
+
+In this challenge, you will write a function `is_even(n: i32) -> bool` that checks if a given number is even or odd using an `if-else` statement. The function should return `true` if the number is even, and `false` if it is odd.
+
+## Requirements
+
+- The function should take an integer as input.
+- Use an `if-else` statement to determine if the number is even.
+- Return `true` if the number is even.
+- Return `false` if the number is odd.
+
+## Example
+
+```rust
+assert_eq!(is_even(4), true);
+assert_eq!(is_even(7), false);
+assert_eq!(is_even(0), true);
+assert_eq!(is_even(-2), true);
+assert_eq!(is_even(-3), false);
+```
