C++ Function List

Question

I'm working on a fairly complex project, a custom encryption routine if you will (just for fun) and I've run into this issue in designing my code layout. I have a number of functions that I want to be able to call by index. Specifically, I need to be able to call one randomly for the encrypt process, but then address that by a specific index in the decrypt process. I was considering a classic function array, but my main concern is that a function array would be tricky to maintain, and a little ugly. (The goal is to get each function pair in a separate file, to reduce compile times and make the code easier to manage.) Does anyone have a more elegant C++ solution as an alternative to a function array? Speed isn't really an issue, I'm more worried about maintainability. -Nicholas JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

Answer 1

What's wrong with function array? You need to call functions by index. So they must be put into some "indexable by index" structure somehow. Array is probably the simplest structure that suits this need. Example (typing out of my head, might not compile): struct FunctionPair { EncodeFunction encode; DecodeFunction decode; }; FunctionPair g_Functions[] = { { MyEncode1, MyDecode1 }, { MySuperEncode, MySuperDecode }, { MyTurboEncode, MyTurboDecode }, }; What is "ugly" or "hard to maintain" in the approach above?
