More on Handling Basic Data Types
Have you ever wanted to learn how basic types of C++ variables interact in complex situations? Ivor Horton explains this, and also describes some interesting features of C++. This article is from chapter 3 of Ivor Horton's Beginning ANSC C++ The Complete Language (Apress, 2004; ISBN 1590592271).
IN THIS CHAPTER, I expand on the types that I discussed in the previous chapter and explain how variables of the basic types interact in more complicated situations. I also introduce some new features of C++ and discuss some of the ways that these are used.

Use XML to document C# code (Part 1).
Xml is one of the best things happened to Web world and if you are familiar with XML then you are going to love ability to use it for documenting C# code. Advantage ? It lets you generate documentation from your C# code. For those who know Java, its almost the same feature as JavaDoc, personally I think its only better. Reason? It uses XML and if used with XSLT you can do wonders with the way your documentation looks with no hard work.
So how does it work? Basically you can write comments in XML format in your C# code and then C sharp compiler allows you to generate XML file containing the documentation when you compile the code. Lets see how does this all really works.
