Rust - assignment operators example

The example below shows the usage of assignment and compound assignment operators:

= Assignment operator
+= Addition AND assignment operator
-= Subtraction AND assignment operator
*= Multiply AND assignment operator
/= Division AND assignment operator
%= Modulo AND assignment operator

fn main() {
  let mut a = 25;

  println!("a = {} \n", a);

  //Addition AND assignment operator
  a += 5;
  println!("a += 5 makes a =  {}", a);

  //Subtraction AND assignment operator
  a -= 8;
  println!("a -= 8 makes a = {}", a);

  //Multiply AND assignment operator
  a *= 4;
  println!("a *= 4 makes a = {}", a);

  //Division AND assignment operator
  a /= 2;
  println!("a /= 2 makes a = {}", a);

  //Modulo AND assignment operator
  a %= 5;
  println!("a %= 5 makes a = {}", a);
}

The output of the above code will be:

a = 25 

a += 5 makes a =  30
a -= 8 makes a = 22
a *= 4 makes a = 88
a /= 2 makes a = 44
a %= 5 makes a = 4
