The Ultimate Guide to Rust Programming

Exercises

Explore practical exercises that help you understand function definition, function calls, and program compilation in Rust. Learn to fix compile errors, create helper functions, and use macros effectively to produce specific program output. This lesson sharpens your skills in writing and manipulating Rust functions for better programming fluency.

We'll cover the following...

Exercise 1

Will the program compile? Why, or why not? If not, try to fix it.

Rust 1.40.0
fn main() {
    42
}

Exercise 2

Will the program compile? Why or why not? If not, try to fix it.

Rust 1.40.0
fn main() {
    println!("{}", 42)
}
