rustHow do I get the last character from a string in Rust?

The easiest way to get the last character from a string in Rust is to use the chars() method. This method returns an iterator over the characters of a string. To get the last character, we can use the last() method on the iterator.

let s = "Hello";
let last_char = s.chars().last().unwrap();
println!("The last character of {} is {}", s, last_char);

Output example

The last character of Hello is o

Code explanation

• let s = "Hello": This line declares a string variable s and assigns it the value "Hello".
• let last_char = s.chars().last().unwrap(): This line uses the chars() method to get an iterator over the characters of the string s. The last() method is then used to get the last character from the iterator. The unwrap() method is used to get the character from the Option type returned by last().
• println!("The last character of {} is {}", s, last_char): This line prints the last character of the string s.
