rust month to quarter

To convert a given month to a quarter in Rust, you can use a match statement or an if-else condition to determine the corresponding quarter based on the month. Here's an example using a match statement:

fn month_to_quarter(month: u32) -> Option<u32> {
    match month {
        1 | 2 | 3 => Some(1),
        4 | 5 | 6 => Some(2),
        7 | 8 | 9 => Some(3),
        10 | 11 | 12 => Some(4),
        _ => None,
    }
}

fn main() {
    let month = 7;
    let quarter = month_to_quarter(month);
    match quarter {
        Some(q) => println!("Month {} is in quarter {}", month, q),
        None => println!("Invalid month"),
    }
}

In the above code, the function month_to_quarter takes a month parameter and returns an Option<u32> representing the quarter. The match statement checks the value of the month parameter and assigns the corresponding quarter value. If the month is not within the range of 1 to 12, it returns None.

In the main function, we call month_to_quarter with a sample month value of 7. We then match the result of month_to_quarter and print the corresponding quarter value if it exists, otherwise we print "Invalid month".

You can modify the code to suit your specific needs.
