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.
