Hello World
#include <iostream> int main() { std::cout << "Hello World!" << "\n"; }	fn main() { println('Hello World!') }
Vector initialization
std::vector<int> numbers = {1, 2, 3, 4};	numbers := [1, 2, 3, 4]
Add an element to a vector
numbers.push_back(5);	numbers << 5
Printing a vector
std::copy(numbers.begin(), numbers.end(), std::ostream_iterator(std::cout, " ")); std::cout << '\n';	println(numbers)
Filtering a vector
std::copy_if(numbers.begin(), numbers.end(), std::back_inserter(bar), [](int i){ return i % 2 == 0; });	numbers.filter(it % 2 == 0)
Reading a file
#include <iostream> #include <fstream> std::ifstream f("path"); std::string text; text.assign(std::istreambuf_iterator(f), {}); if (!f) std::cerr << "error reading from file\n";	import os text := os.read_file(path) or { eprintln(err) }
