1 Removing Character at Index from "Hello World" String

In this example,

We create a string named str1 with a value of "Hello World".
We use string slicing to remove the character at the specified index.
Finally, we print the modified string.

Rust Program

fn main() {
    let mut str1 = String::from("Hello World");
    let index_to_remove = 6;
    str1.remove(index_to_remove);
    println!("Modified string is: {}", str1);
}

Output

Modified string is: Hello orld

2 Removing Character at Index from "apple" String

In this example,

We create a string named str2 with a value of "apple".
We use string slicing to remove the character at the specified index.
Finally, we print the modified string.

Rust Program

fn main() {
    let mut str2 = String::from("apple");
    let index_to_remove = 2;
    str2.remove(index_to_remove);
    println!("Modified string is: {}", str2);
}
