Programming Language Evaluation

A list of simple tasks to perform when learning or evaluating a new language. Each of these should be able to be completed in a few hours, and will help to get the feel of the language and its standard libraries. A well-rounded set of evaluation tasks will help ensure all parts of the language are exercised. You might also write some tests to demonstrate implementation correctness.

Basics

  1. Hello world
  2. Read lines from a text file and output them in sorted order
  3. Read numbers from a text file and output the mean and standard deviation
  4. Given an amount of money and a list of coin denominations provided on the command line, output all the possible ways to make change
