In Cairo, a string is a collection of characters stored in a felt252. Strings can have a maximum length of 31 characters.

Examples of strings:

use debug::PrintTrait;
fn main() {
    let x = 'Cairo is awesome';
    let c = 'A';

To run this example, first copy the code in a new file and then run cairo-run --single-file file_name in your terminal.
