Lab 4: Wordle ahead

Due: 2026-03-09 at 23:59

In this lab, you’ll learn how to

  • work with individual characters in a string;
  • write colored text to the terminal;
  • flush output to standard out;
  • call functions defined in other modules;
  • implement a command-line utility;
  • parse command-line arguments;
  • read from standard in or from a file; and
  • handle errors.

Preliminaries

First, find a partner. You’re allowed to work by yourself, but I highly recommend working with a partner. Click on the assignment link. One partner should create a new team. The team name cannot be the same name used for a previous lab. The second partner should click the link and choose the appropriate team. (Please don’t choose the wrong team, there’s a maximum of two people and if you join the wrong one, you’ll prevent the correct person from joining.) You cannot choose a team name you’ve used previously.

Once you have accepted the assignment and created/joined a team, you can clone the repository and begin working.

Compiler warnings and errors

Make sure your code compiles and passes clippy without errors or warnings. That is, running

$ cargo clean
$ cargo build
$ cargo clippy

should build your program without errors or warnings.

Formatting

Your code must be formatted by running cargo fmt.
