✐ Examples

1 Concatenate Strings in Vector

In this example,

We create a vector named strings containing multiple strings.
We call the `join()` method on the vector strings, passing a separator string as an argument.
The `join()` method concatenates all the strings in the vector, separated by the specified separator.
Finally, we print the concatenated string to standard output.

Rust Program

fn main() {
    let strings = vec!["Hello", "World", "in", "Rust"];
    let concatenated_string = strings.join(" ");
    println!("{}", concatenated_string);
}

Output

Hello World in Rust
