Examples:
Hello, World! - Rust (415):
use std;
import std::io;
fn main() {
io::println("Hello, World!");
}
Factorial - Rust (416):
This example uses recursive factorial definition. Due to uint
overflow values of 13! and larger are calculated incorrectly.
use std;
import std::io;
fn factorial(x: int) -> uint {
if (x <= 1) {
ret 1u;
} else {
ret (x as uint) * factorial(x - 1);
}
}
fn main() {
let i = 0;
while i <= 16 {
io::println(#fmt("%d! = %u", i, factorial(i)));
i = i + 1;
}
}
Fibonacci numbers - Rust (417):
This example calculates Fibonacci numbers recursively.
use std;
import std::io;
fn fibonacci(x: int) -> int {
if (x <= 2) {
ret 1;
} else {
ret fibonacci(x - 1) + fibonacci(x - 2);
}
}
fn main() {
let i = 1;
while i <= 16 {
io::print(#fmt("%d, ", fibonacci(i)));
i = i + 1;
}
io::println("...");
}
