• Where can I find some good tutorials for C++

  - by Rob

  My friend has convinced me to start learning some C++, so my question is simple: where can I find some good tutorials for it? But please don't link me to the usual dry boring tutorials that only tells you the function syntax, I need more thorough explanations. I get sidetracked very easily, and I need tutorials that are more on a human level, that I'll not only learn from, but enjoy reading as well. So I'd appreciate any links that would help :)

  - by eqbridges

  I would like to convert this /bin/sh syntax into a widely compatible Windows batch script: host=`hostname` echo ${host} How to do this so that it'll work on any Windows Vista, Windows XP, and Windows 2000 machine? To clarify: I would then like to go on in the program and use the hostname as stored in the variable host. In other words, the larger goal of the program is not to simply echo the hostname.

• Multiple Regex on String

  - by George

  How can I apply multiple regexs to a single string? For instance, a user inputs the following into a text area: red bird blue cat black dog and I want to replace each carriage return with a comma and each space with an underscore so the final string reads as red_bird,blue_cat,black_dog. I've tried variations in syntax along the lines of the following so far: function formatTextArea() { var textString = document.getElementById('userinput').value; var formatText = textString.replace( new RegExp( "\\n", "g" ),",", new RegExp( "\\s", "g"),"_"); alert(formatText); }

For example: $("#form_survey").validate({ rules: { a_ +i: {max:12, maxlength:2}, }, messages: { a_ +i:{ max: "That's too much!" } } Where the "+i" is the ideal increment of +1... Should be easy, I'm just stuck on syntax...

  - by ?????

  I'm running Groovy Version: 1.7.0 JVM: 1.6.0_17 (Update -- I just upgraded to 1.7.1 and get the same errors!)

For example: This code won't compile or run, and gets the error above. enum VehicleStatus { OFF, IDLING, ACCELERATING, DECELARATING } class Vehicle { Long id Long version VehicleStatus status }
