Create random strings
Rust Programming Language
Problem
In Rust, we can generate random strings using the rand crate. Here's an example program that demonstrates how to create a random string of a given length.
Input
use rand::Rng;
fn main() {let length = 10;let mut rng = rand::thread_rng();let random_string: String = (0..length).map(|_| rng.gen_range(b'a', b'z') as char).collect();println!("{}", random_string);}{codeBox}
Output
kfsqjwslct{codeBox}
Explanation
In this program, we first import the rand::Rng trait. We then set the length of the random string we want to generate to 10.
Next, we create a new rand::thread_rng() object, which is a thread-local random number generator. We then generate a random string of length 10 by using the map() method to generate a random character for each position in the string. We use the gen_range() method to generate a random integer in the range of b'a' to b'z' (inclusive), and then convert the integer to a character using the as char syntax. Finally, we collect the generated characters into a String using the collect() method.
