Part of the Fundamentals section of Coddy's Rust journey — lesson 40 of 75.

The continue statement stops the current iteration and continues to the next iteration. For example:

for i in 3..9 {
    if i == 5 {
    	continue;
    }
    println!("{}", i);
}

The loop will iterate through all of the numbers. when it reaches i=5 it will skip that iteration and continue to the next one. The output is:

Notice, number 5 is not in the output.

Challenge

Beginner

You are given a code which prints the numbers from 1 to 20 (including).

Your task is to add if and continue statements so that only the even numbers will be printed (2, 4, 6, ...).

Try it yourself

fn main() {
    for i in 1..=20 {
        println!("{}", i);
    }
}

Test yourself

This lesson includes a short quiz. Start the lesson to answer it and track your progress.
