 | A religion typically consists of a being (or a collection of beings) that exists. Google isn't exactly a being, but it does exist. Some people even consider it a godlike entity. For a typical god, you provide a ritual or some kind of prayer. This prayer typically takes a long …  |

Here's a correction-- [code=c++] #include <iostream> #include <fstream> using namespace std; const int MAX = 30; struct node { char base; node* next; }; node* head; void initialise(); void insertion(char); void printlist(node& root); int main() { ifstream ins; char filename[MAX]; int count = 0; // initialize … |

| | Classes can be used for many things... The Programming perspective: -Restricting access to encapsulated data/ standing in for the same type (Proxy) -Abstractions for future data (Strategy, Bridge) -Adding functionality to existing objects with the same interface (Decorator) -Adapting an object to the interface of another (Adapter) -Providing a commonality … |
 | Re: MySQL++ I hope I'm not out of place by asking this, but does it have something to do with calling conventions? [URL="http://msdn.microsoft.com/en-us/library/zxk0tw93(VS.71).aspx"]>_>[/URL] |
 | From what I understand, all objects are saved as .dat files for Java to reinterpret back into an object during deserialization. To save files with an extension, I'd assume you'd use FileOutputStream and specify the kind of File you'd like to save. If you mean to save an Object into … |
| | I've tried the above using tests with unsigned __int8, __int16, __int32 and __int64 (for the class and cast) and received either contiguous or non-contiguous results. More likely than not, we missed something (like padding factor for certain values), though I can't confirm this... *Heads for the C++ Object Model* >_> |
| | Are you required to use C headers/functions or are you allowed to use C++? |
| | I've just begun reading the AoA book, and the author points out that one of the benefits of Assembly is that it is faster than any HLL and can provide algorithms that HLL's cannot. I hope that's helpful >_> |

| | Re: Address book It sounds like you need a map, or an algorithm to determine a match for a set amount of values. Personally, to get things working, I'd take the easy way out until I found a more efficient solution. What immediately comes to mind is something like this-- [code=c++] #include <iostream> … |

| | Strongly recommended books-- -Java, How To Program 7th edition (Deitel & Deitel) -Head First Design Patterns I suggest reading both in parallel. You will find both to be an easy read (in my opinion at least) until you get to harder concepts in the 16+ chapters of Deitel&Deitel book or …  |
| | I was tinkering around with code in C++ last night trying to make a template algorithm that would be evaluated at compile time and also print information. Unfortunately, because std::cout and std::cin are references to objects and they aren't considered built in types (directly at least), I suppose the compiler … |
| | Re: static Like previously stated, the static modifier allows Objects that consist of that static data type to share data from the same address. One word of warning though - static variables are initialized once and only once! Not only that, but the scope of static is contained within the JVM it … |

| | [QUOTE=Ancient Dragon;682681]>>are STL containers faster then c-style arrays? No. you can't get any faster access than c style arrays. But that isn't the point -- c++ [B]STL eliminate many of the problems with c style arrays, such as dynamic array allocations. vector and other containers expand/contract by themselves, and they … |
| | The problem is that your Charact method is stuck in the while loop. You obtain the length of the file and state the conditon numChar != -1. Keep in mind what data types are for. They store a copy of the data they accept. Here you're calling f.length() and placing … |

If so, I would appreciate a few titles to look into! =) The purpose of doing this research is to further my understanding with programming. If I can better understand the File Allocation Table as well as other popular File-Systems today …  |
| | Re: Project Help I can see a few ways of this being done... First of all, why use an array? You can easily use a LinkedList (and even a nested LinkedList) to get the job done. Chances are you'll only need a 1 LinkedList anyways. For example, you can track time using a … |

| | JSP/JSF is the way to go for this project! The reason? It sounds to me like you're forming a front-end for Database management. From what I understand, JSP has support for Database management, allowing one to make a visual representation of a database, though it isn't incredibly easy to implement. … |

| | Is this the timer in swing or util? If swing then you just need to place an if-else in the actionPerformed method that the timer is firing. I'd use a circular (or random) iterator for the actions that you need to take place during calls to the actionPerformed method. |
| | Errors 1, 2 (and most likely 3) are generated because third.getPages is being parsed as a variable that exists within the Class associated by the object third.

| | I've always wondered how GObjects had such significantly improved pixel-rendering over objects sketched out by the Graphics object in paint and paintComponent methods. What approach should I take to receive the same effect for big images that are say 1024x960, when using simple Graphics? Is there some way to traverse …  |
| | An interface is a static context template that classes can implement. The methods within the interface have no body and must be of public access. In addition, interfaces can also contain "constants" in which data is declared and defined. An example-- [code=java] public interface MyInterface{ public final int VALUE = … |
| | For simplicity, I helped a bit with subString, though I haven't tested it thoroughly enough to track if it will always be true. I did however provide an explanation on what was done to come up with a method solution-- [code=java] /** Hi there. i am trying to create an … |
