Last Updated : October 04, 2021

Problem Statement

Here, we will create an integer variable, and then we will find the weekday from week number using the match statement without returning the value.

Program/Source Code

The source code to demonstrate the match statement without returning the value is given below. The given program is compiled and executed successfully.

// Rust program to demonstrate the 
// match statement without returning value

fn main() {
    let mut weekNum:i32 = 2;
    
    match weekNum {
    1=> println!("Sunday"),
    2=> println!("Monday"),
    3=> println!("Tuesday"),
    4=> println!("Wednesday"),
    5=> println!("Thursday"),
    6=> println!("Friday"),
    7=> println!("Saturday"),
    _=> println!("Invalid week number")
    };  
}

Output
