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 …

Whoo O_O! Pretty fun XD I can't seem to win! Right when I think I will, I end up landing on a mine XD =)

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 …

In times like this I'd either write pseudo-code or a process of how I want the code to work. such as... //The maximum amount of stars printed is the argument the user/programmer decides //the stars stack onto each other until they reach max value, then descend to zero knowing this, …

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.

Solves simple string-based expressions. Currently only supports integers, but can easily be expanded to support float-types.
