# c4

Rust C-like for-loop macro.

```rust

fn main() {

    c4! {

        for (let mut i = 1; i <= 10; i += 1) {

            println!("9 * {:<2} = {}{}", i, i - 1, 10 - i);

        }

    }

    c4! {

        for (

            let (mut i, mut j) = (0, 0),

            let mut s = "some dummy word".to_string();

            i * j <= s.len();

            i += 1,

            s = format!("{} {} {}", &s, i, j)

        ) {

            j += 1;

            println!("i: {}; j: {}; s: {}", i, j, s);

        }

    }

}
