Welcome to our third series! Now that you have a strong foundation in Rust's basic syntax and data types, it's time to start building programs that can interact with the user. In this article, we will explore how to get input from the user and display output to the console using Rust's standard I/O library.
In the previous article, we learned how to get input from the user as a String. However, to build useful applications, we often need to convert that string into a different type, like a number. This process is called parsing. In this article, we'll explore how to parse strings into numbers and handle the potential errors that can occur.
It's time to put everything you've learned in this series into practice. We've covered variables, operators, and handling user input. Now, we'll combine all of these concepts to build a complete, interactive program: a simple command-line calculator.
In Part 1 of our Guessing Game project, we set up the project and generated a random secret number. Now, it's time to add the core logic of the game: getting the user's guess and comparing it to the secret number.
