Hello World

Introduction

Instructions

The classical introductory exercise. Just say "Hello, World!".

"Hello, World!" is the traditional first program for beginning programming in a new language or environment.

The objectives are simple:

• Modify the provided code so that it produces the string "Hello, World!".
• Run the test suite and make sure that it succeeds.
• Submit your solution and check it at the website.

If everything goes well, you will be ready to fetch your first real exercise.

Track Specific Notes

Your solution may be a procedure that returns the desired string or a variable whose value is that string.

Running and testing your solutions

From the command line

Simply type make chez if you're using ChezScheme or make guile if you're using GNU Guile. Sometimes the name for the scheme binary on your system will differ from the defaults. When this is the case, you'll need to tell make by running make chez chez=your-chez-binary or make guile guile=your-guile-binary.

From a REPL

• Enter (load "test.scm") at the repl prompt.
• Develop your solution in hello-world.scm reloading as you go.
• Run (test) to check your solution.

Failed Test Cases

If some of the test cases fail, you should see the failing input and the expected output. The failing input is presented as a list because the tests call your solution by (apply hello-world input-list). To learn more about apply see The Scheme Programming Language -- Chapter 5
