Choose Rust for memory safety and concurrency without garbage collection, C++ for maximum performance and legacy ecosystem access, or C# for rapid development and tooling support. Rust prevents data races at compile time using ownership, C++ offers manual memory control with undefined behavior risks, and C# provides a managed runtime with automatic garbage collection.
// Rust: Compile-time safety via ownership
fn main() {
let data = vec![1, 2, 3];
let handle = std::thread::spawn(move || {
println!("{:?}", data); // Safe: ownership moved
});
handle.join().unwrap();
}
// C++: Manual control, risk of dangling pointers
std::vector<int> data = {1, 2, 3};
std::thread t([&data] {
std::cout << data[0]; // Risk: data might be destroyed
});
// C#: Managed safety via garbage collection
var data = new List<int> {1, 2, 3};
Task.Run(() => Console.WriteLine(data[0])); // Safe: GC handles lifetime
