Questions tagged [code-translation]

For questions regarding the translation of code from one programming language to another. NOTE that asking to have your code translated is not suitable for Stack Overflow.

Translating code from one programming language to another can be as tricky as translating between natural languages. This is due to the fact that languages implement different sets of features and are often designed with very different goals. What comes as a built-in function in one language may have to be developed from scratch (or at least require a library) to achieve the same functionality in another.

An appropriately formed question might be "How do I translate this statement", or "What are the differences between these two statements in different languages". It is not appropriate to ask for your code to be translated.
