rustRust function example

A Rust function is a block of code that performs a specific task. It can take parameters, and can return a value. Here is an example of a Rust function that takes two parameters and returns the sum of them:

fn add_two_numbers(x: i32, y: i32) -> i32 {
    x + y
}

The output of this function would be the sum of the two parameters, for example:

add_two_numbers(2, 3) // Output: 5

The ## Code explanation

• fn add_two_numbers(x: i32, y: i32) -> i32 { - This is the function declaration, which includes the function name, parameters, and return type.
• x + y - This is the body of the function, which contains the code that will be executed when the function is called.
• add_two_numbers(2, 3) - This is an example of calling the function, passing in two parameters.
