Rust: 115 Characters

[DarkRTA]

extern { fn putchar(x: usize); } // links to putchar() in libc.

fn main() {
    let x = true as usize;       // x = 1
    let y = x + x + x;           // y = 3
    let z = (y << x + y) + x;    // z = 49
    for c in z..=z + y {         // loop c from 49 (z) to 52 (z + y)
        unsafe { putchar(c); }   // write c to stdout. extern functions are unsafe
    }
}

My dumbass at 1am forgot true existed and I ended up shaving off about 20 characters.
I highly doubt this can get any smaller without a different approach. x could have been reused by making it mutable but that wouldn't affect the character count.
