rustHow to uppercase a string in Rust

You can uppercase a string in Rust using the to_uppercase() method. Here is an example:

let my_string = "hello world";
let uppercase_string = my_string.to_uppercase();
println!("{}", uppercase_string);

Output

HELLO WORLD

Explanation:

• let my_string = "hello world";: This line declares a variable my_string and assigns it the value of the string "hello world".
• let uppercase_string = my_string.to_uppercase();: This line calls the to_uppercase() method on the my_string variable, and assigns the result to the uppercase_string variable.
• println!("{}", uppercase_string);: This line prints the value of the uppercase_string variable to the console.
