rustHow do I iterate over a string in Rust?

Iterating over a string in Rust is done using the chars() method. This method returns an iterator over the characters of a string.

Example code

let my_string = "Hello World!";

for c in my_string.chars() {
    println!("{}", c);
}

Output example

H
e
l
l
o

W
o
r
l
d
!

Code explanation

• let my_string = "Hello World!";: This line declares a string variable.
• for c in my_string.chars(): This line starts a for loop that iterates over the characters of the string.
• println!("{}", c);: This line prints each character of the string.
