Rust program to demonstrate the match with the block of statements

Rust | match with the block of statements example: Given a number (week number), we have to find the weekday.
Last Updated : October 04, 2021

Problem Statement

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

Program/Source Code

The source code to demonstrate the match with the block of statements is given below. The given program is compiled and executed successfully.

// Rust program to demonstrate the 
// match with block of statements

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

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

Output

Match found for 2
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 match with block statements and printed the result.
