Submitted by Nidhi, on October 04, 2021

Problem Solution:

Here, we will create an integer variable, and then we will find the weekday from week number and print the result.

Program/Source Code:

The source code to demonstrate the match statement is given below. The given program is compiled and executed successfully.

// Rust program to demonstrate 
// the match statement

fn main() {
    let mut weekNum:i32 = 2;

    let day = match weekNum {
    1=> "Sunday",
    2=> "Monday",
    3=> "Tuesday",
    4=> "Wednesday",
    5=> "Thursday",
    6=> "Friday",
    7=> "Saturday",
    _=> "Invalid week number"
    };
    
    println!("Week day is: {}",day);
}

Output:

Week day is: Monday

Explanation:

Here, we created an integer variable weekNum with an initial value of 2. Then we found the weekday from week number using the match statement and printed the result.
