Rust | match statement without returning the value example: Given a number (week number), we have to find the weekday.
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 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:

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 without returning value and printed the result.
