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.
Submitted by Nidhi, on October 04, 2021

Problem Solution:

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.
