I'm storing a bunch of supposedly-unique item IDs as a key and the file locations as the value in a hash table while traversing a table. While I am running through it, I need to make sure that they key/location pair is unique or throw an error message. I have the hashtable set up and am loading the values, but am not sure what to test:...
stupid question but this statement is worthless int a; if (a != null) since an integer var is automatically set to null by the compiler when defined to check integers always check if a >= 0 correct? ...
Ok, so I've read about this a number of times, but I'm yet to hear a clear, easy to understand (and memorable) way to learn the difference between: if (x | y) and if (x || y) ..within the context of C#. Can anyone please help me learn this basic truth, and how C# specifically, treats them differently (because they seem to do the ...

I found today a comment in a source file: // - no longer compare BOOL against YES (dangerous!) So my question is: Is comparing BOOL against YES in Objective-C really that dangerous? And why is that? (Can the value of YES change during runtime? Like NO is always 0 but YES can be 1, 2 or 3 - depending on runtime, compiler, your linke...
I've been programming as a consultant for years, and I adore my work, which involves a lot of object-oriented analysis and design of software systems using managed languages (ie. software engineering). But I'd like to get a doctorate eventually, and it bothers me that I never really "got" Computer Science theory. In university I only did...
I've been attempting to learn programming (in C#) for a few years now. The problem I've had is that I'd know what I want to do (or what I want the program to do), but no idea on how to actually implement it. So I often wonder what it is I'm lacking. Is the mindset of a programmer somehow different, and I've yet to condition myself to tha...
Do you need to have good spatial sense to be a good programmer? I have next to nothing of it (I think it has to do with the differing vision of my eyes). I've already coded quite little things but wonder if this interferes with the ability to 'imagine' the assembly of the code in case of a more complex program? Sorry for my english, ...
im new to Java and have the following question regarding inner classes: when implementing a inner class do i need to declare its attributes and methods scope i.e. public, private, protected? EDIT: with the absense of delegates like in C# could someone mention how best to implement a messaging system in Java that enables communication b...

When I write code in C, I often get confused when the questions/problems demand the usage of the output for further calculations. For example, if we have to print an array and then add only the prime numbers from it? or something which is similar. I get stuck and I don't know how to tackle such questions. As in when we take input from...
