Question 1

True or false: Rust was the most loved language on Stack Overflow surveys for eight consecutive years.

Accepted Answer

True. Rust topped Stack Overflow's 'Most Loved' category from 2016 to 2023, reflecting strong developer satisfaction due to its safety and performance.

Question 2

True or false: Rust was originally developed by Mozilla as a research project in 2010.

Accepted Answer

True. Rust started as a personal project by Graydon Hoare at Mozilla Research in 2010, later becoming an open-source language with community backing.

Question 3

True or false: Rust's standard library includes a built-in HTTP server for web development.

Accepted Answer

False. Rust's standard library does not include an HTTP server; instead, external crates like `hyper` or `actix-web` are used for web development.

Question 4

True or false: Rust's ownership model guarantees memory safety without needing a garbage collector.

Accepted Answer

True. Rust uses compile-time ownership rules and borrowing to prevent memory leaks and dangling pointers, eliminating the need for a runtime garbage collector.

Question 5

True or false: Rust allows multiple mutable references to the same data in the same scope.

Accepted Answer

False. Rust's borrow checker forbids multiple mutable references to the same data in the same scope to prevent data races at compile time.

Question 6

True or false: Rust's `async/await` syntax was introduced in the 2015 edition to simplify concurrency.

Accepted Answer

False. `async/await` was stabilized in Rust 1.39 (2019), not the 2015 edition; earlier concurrency relied on threads and futures via crates.

Question 7

True or false: Rust's `unsafe` keyword completely disables all safety checks, including memory and type safety.

Accepted Answer

False. `unsafe` only enables five specific operations (e.g., dereferencing raw pointers) but still maintains Rust's type system and ownership rules.

Question 8

True or false: Rust's compiler can detect and prevent integer overflow in debug mode by default.

Accepted Answer

True. In debug mode, Rust panics on integer overflow; in release mode, it wraps using two's complement for performance, but this is a deliberate design choice.
