I think I recall my professor saying-- "The way search engines work is through Hash-indexing. All you have to do to search is Hash-it-up!" Or something along those lines. It might be wise to look up HashMap or HashSet to see how you can locate certain values through indexing, though …

This is a remake of the Simple Equation Solver snippet that is written in Java. This is an equivalent version written in C++.

Hmm... I've made it my top priority to get a Master's and Ph.D in Computer Science and Software Systems... however I'd like to know what a suitable Master's Thesis would be? I'm thinking about making a book, maybe 6000 pages long, pertaining to nothing but Software ideals and technology. This …

Is this really a fair comparison? With C# you are using the CLR to indirectly use your OS and in C++ you are directly using the OS. If you want this to be a fair comparison, try running the code using the CLR in C++ also.

Here's a toughy. Write the Snaker program, using either a JFrame, GraphicsProgram or a JApplet (any GUI of your choice really). Your snaker object will start off as one circle. That circle represents a head. The body grows by encountering "snake-food" on the screen. When the head runs over the …

This is a post on blackboard from a class-mate of mine-- [icode] /** * Posted by 'Gregg' */ ptr_practice1.cpp (3.139 Kb) When you create a 2 dimensional array on the stack, both the row and column values must be known at compile time, which is why you must use either …

I'm fairly certain that before you can load an image you have to prepare it first. System.out.println(prepareImage(img, 300, 400, this)); use this after you attempt to get the Image specified by your source.

Hmm, can that union trick work with reinterpret_cast also? i.e.-- [code=c++] #include <iostream> using namespace std; int main(){ union{ short *a; float *b; }; float value = .1f; b = &value; std::cout << *a << std::endl; short *s; float *f; f = &value; s = reinterpret_cast<short*>(f); std::cout << *s << …

It may be possible that Java won't support an image-type in future releases and therefore not provide Serialization support for it but that depends on what it is. I remember getting warning pertaining to images of a specific class and that class might be the culprit but I can't completely …

I found some links that rendered Images to .gifs, which seemed useless at first but then I looked into the Image class and all of the "helper" classes for its methods. I think I'll try to look into how to read the pixels on a screen into an array (or …

Typically when you overload something (a function for example), you're giving a new option as to how the client/programmer can use that function. Polymorphism is slightly more difficult to describe. It's as if you're giving new meaning to an existing procedure in a way that is transparent to the client. …

I think the only way to create a "virtual constructor" is to make a virtual method that returns the object inquestion, where derived classes return a copy of their type instead of the base classes return implementation. By casting a derived type to a base type and invoking the virtual …

This is a simple Search Engine that contains tokenized words as keys, in which they will return values associated with them in an ArrayList. All that is required is a text file from a valid extension.

I can already see you using the Bridge and/or Strategy pattern from the specs. You'll also most likely end up using the Observer pattern. Try not to be distracted by the specs too much. Break down the problem. You're limited to 1000 points of units. What I'd do is have …

The problem may be that the compiler sees a possibility of your .cpp file attempt to define something that doesn't exist, since your header file is conditionally defined. You can make it, such that, the text in your implementation file is read by the compiler if and only if the …
