C++14 was as much a bug fix and clean up of C++11 as anything, so it's an incremental improvement. I see no evidence of it producing mixed results, what have you seen? C++17 is new, so the jury is still out. -- Ian. |

Unless you are seriously resource constrained I think C++ is a better tool than C. But C still has its place. I can't imagine why you should want to use a tool that was designed back in the 1970s (or maybe 1988) these days, unless you have to. I use VI from time to time - git checkins, for example. But there are better editors for more complex work. But I guess we'll have to agree to differ on this :) Andy |

I /think/ that code is structured something like the following: if (!Mark || Secs>(Mark+3)) { Mark = Secs; Cnt = 1; } else if (++Cnt>3) { Mark = Secs; Cnt = 1; Keyboard = FindWindows(0,"..."); if (Keyboard) { SendMessage(Keyboard,274,0,0); } else { 0; } Launch("..."); } else { 0; } } If so, then those dummy 0 expressions might only be there as the required third operand of ?:, so are not really necessary: if (!Mark || Secs>(Mark+3)) { Mark = Secs; Cnt = 1; } else if (++Cnt>3) { Mark = Secs; Cnt = 1; Keyboard = FindWindows(0,"..."); if (Keyboard) { SendMessage(Keyboard,274,0,0); } Launch("..."); } } This still takes double the number of lines, but is much easier to follow. (Here I admit I cheated by using a tool to decipher the structure. But you shouldn't need to use any tool.) -- bart |

I usually only see Arduinos in terms of potential customers who have got a vague prototype or proof of concept using an Arduino, and want to develop a product. Arduinos are great for getting people interested in embedded programming, and have spawned a wide selection of off-the-shelf cards for prototyping, but they have a counter-productive design for the development system. It combines the worst of C with the worst of C++, hides all the useful stuff in the toolchain, skimps over important details so that people who learned with Arduino can't program on other systems, and gives a false impression that embedded development is something quick and easy. If you understand the limitations of the system, it can be a useful idea - if not, it is worse than useless. And Arduino programs have a "main()". It is just hidden from the user. |
