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.

First of all, I know that nested functions are not supported by the C standard. However, it's often very useful, in other languages, to define an auxiliary recursive function that will make use of data provided by the outer function. Here is an…

I have a program written in C# that receives data from a third party server and processes it into a series of integers (they are streaming rapidly). The program is written in C# because the third party provides classes to process the data, but only…
