rustHow to iterate over string in Rust

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

Example:

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 declares a string variable called my_string and assigns it the value "Hello World!".
• for c in my_string.chars(): This starts a loop that iterates over each character in the string my_string. The current character is stored in the variable c.
• println!("{}", c);: This prints the current character stored in the variable c.
