  let no1 = 200;
  let bool1 = true;
  // create clones
  let clone1 = char1.clone();
  let clone2 = string1.clone(); 
  let clone3 = no1.clone(); 
  let clone4 = bool1.clone(); 
  // print clone values
  println!("{}", clone1);
  println!("{}", clone2);
  println!("{}", clone3);
  println!("{}", clone4);
}

Explanation

In the code above:

  • In lines 3–6: We create some variables and initialize them with some values.
  • In lines 9–12: We clone the values of the variables using clone().
  • In lines 15–18: We print the values of the clones to the console screen.
