rustHow to loop string chars in Rust

Looping through a string in Rust is a simple process. The chars() method can be used to iterate over the characters of a string. The following example code will loop through each character of a string and print it out:

let s = "Hello World";

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

Output example

H
e
l
l
o

W
o
r
l
d

The code works by using the chars() method to get an iterator over the characters of the string. The for loop then iterates over the characters and prints them out.

Code explanation

• let s = "Hello World";: This line declares a string variable s and assigns it the value "Hello World".
• for c in s.chars(): This line starts a for loop that iterates over the characters of the string s. The variable c is used to store each character as the loop iterates.
• println!("{}", c);: This line prints out the character stored in the variable c.
