Rust programming language Quiz

Question 1

What is the syntax to declare a mutable variable in Rust?

Accepted Answer

let mut variable_name = value;. Because 'let mut' declares a mutable variable in Rust.

Question 2

What is the Rust equivalent for a try-catch block?

Accepted Answer

Result. Because 'Result' is a Rust data type that enables error handling in Rust, similar to how try-catch blocks handle exceptions in other programming languages.

Question 3

What is the name of Rust's package manager?

Accepted Answer

Cargo. Because 'Cargo' is the official package manager for Rust programming language.

Question 4

Which operator is used for accessing the value from an Option type in Rust?

Accepted Answer

unwrap. Using `unwrap` on an `Option` will cause the program to panic and terminate if the `Option` is `None`, making it important to ensure that `unwrap` is only used when the presence of a value is guaranteed.

Question 5

What does the '!' operator do in Rust?

Accepted Answer

Negates Boolean value. Because the exclamation mark (!) operator negates the Boolean value, which means it reverses the truth value of a Boolean expression in Rust.

Question 6

Is String a core data type in Rust?

Accepted Answer

No. Because 'String' is a dynamically allocated string type in Rust and is not a core data type.
