Crystal Programming Language

Crystal is a statically-typed, compiled programming language with a syntax reminiscent of Ruby. It aims to combine the expressiveness and developer-friendly features of Ruby with the performance and efficiency of C. Crystal is an ideal choice for high-performance applications, such as web servers, system-level software, and command-line tools. Its type system ensures type safety while still providing the flexibility and elegance of a scripting language. Crystal's concurrency support makes it suitable for building scalable and efficient server applications. Developers often opt for Crystal when they seek a balance between developer productivity and system performance.

Examples of generated Crystal code

The following are examples of some programs created by this Crystal code generator. Note that you may not always get the same code since it is generated by an AI language model which is not 100% deterministic and gets updated from time to time.

Greet User

Program that takes a user's name as input and prints 'Hello' along with the user's name.

Temerpature Converter (Celsius to Fahrenheit)
