Courses / Rust: Ownership without Tears / Lesson 1
1. Hello, Cargo
Every programmer starts here. In this lesson you write a complete program, run it, and change it until it does what you want.
fn longest(words: &[String]) -> &str {
let mut best = "";
for w in words {
if w.len() > best.len() {
best = w;
}
}
best
}
Your turn
Change the program so it greets you by name, then run it in the playground. The checks turn green when the output matches.
