How to get Last Element in Array in Rust - Step by Step Examples



How to get Last Element in Array in Rust ?

Answer

To get the last element in a vector in Rust, you can use the pop() method or array indexing.



✐ Examples

1 Last Element of Given Integer Vector

In this example,

  1. We create an integer vector named numbers with some elements.
  2. We use the pop() method to remove and return the last element of the vector, which gives us the last number.
  3. Finally, we print the value of the last number.

Rust Program

fn main() {
    let mut numbers = vec![1, 2, 3, 4, 5];
    let last_number = numbers.pop().unwrap();
    println!("Last number is: {}", last_number);
}

Output

Last number is: 5

2 Last Element of Given String Vector

In this example,

  1. We create a string vector named fruits with some elements.
  2. We access the last element of the vector using array indexing fruits[fruits.len() - 1] and store it in the variable last_fruit.
  3. Finally, we print the value of the last fruit.

Rust Program

fn main() {
    let fruits = vec!["apple", "banana", "cherry"];
    let last_fruit = fruits[fruits.len() - 1].to_string();
    println!("Last fruit is: {}", last_fruit);
}

Output

Last fruit is: cherry
