In this article we look at the C build process – that is, how we get from C source files to executable code, programmed on the target. It wasn’t so long ago this was common knowledge (the halcyon days of the hand-crafted make file!) but modern IDEs are making this knowledge ever-more arcane.
Compilation
The first stage of the build process is compilation.
The compiler is responsible for allocating memory for definitions (static and automatic) and generating opcodes from program statements. A relocatable […]

The enumerated type (enum) is probably one of the simplest and most underused features of the C and C++ which can make code safer and more readable without compromising performance.
In this posting we shall look at the basic enum from C, how C++ improved on C’s enum, and how C++0X will make them a first class type.
Often I see headers filled with lists of #defines where an enum would be a much better choice. Here is a classic example:
/* adc.h […]
