Variables With If Expressions

Let's use variables in the condition section of our if/else expression. The first step is to bind the values to our variables.

let alfa = 7;
let bravo = 8;

Then, we'll replace the numbers in the condition section of the if statement with the variable names. So, this:

if 7 == 8 {
  ...
}

Becomes this:

if alfa == bravo {
  ...
}

Here's the code for the full example which outputs:

They don't match

SOURCE CODE

fn main() {

  let alfa = 7;
  let bravo = 8;

  if alfa == bravo {
    println!("They match");
  } else {
    println!("They don't match");
  }

}
