If/Else - Rust Programming

In Rust if is an expression, so it can produce a value directly into a binding.

Program

Play the program to let a score choose the pass label.

if_else.rs

fn main() {
    let score = 82;
    let grade = if score >= 80 { "pass" } else { "retry" };
    println!("{grade}");
}

if expression `if ... else ...` evaluates to a value.

comparison `score >= 80` produces a `bool`.

branch value Both branches must produce the same type.
