The series continues today with our first actual C++ code! Today we’ll start with the absolute fundamentals—primitive types and literals—on which we’ll build through the rest of the series. As basic as this topic sounds, some of it can be pretty shocking when coming from a language like C#.

The language’s built-in types should be trivial, but they’re not. There are a lot of little details overlooked by many programmers. Today’s article continues the series by looking at subtleties found in seemingly-obvious language features like strings and integers. Read on to learn some tricks!
When a recent comment asked about string concatenation performance, I realized that there are a lot of ways to build strings in AS3 and I hadn’t tested any of them. Leaving aside the sillier ones like the XML class or joining Array objects, we have two serious contenders: the lowly + operator (i.e. str + str) and the ByteArray class. Which will triumph as the ultimate way to build strings quickly?
