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:
3
4
6
7
8Notice, number 5 is not in the output.
Challenge
BeginnerYou 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, ...).
Cheat sheet
The continue statement stops the current iteration and continues to the next iteration:
for i in 3..9 {
if i == 5 {
continue;
}
println!("{}", i);
}This will print all numbers except 5:
3
4
6
7
8Try it yourself
fn main() {
for i in 1..=20 {
println!("{}", i);
}
}
