Data Initialization and Mathematical Expressions

Abstract

Many questions start to appear when coding moves from defining a few variables into actually doing something. For example, understanding the role and rules of initializing variables with regard to compile time and run-time instantiation is crucial. Constants and their initialization expressions require values which can be determined at compile time, not run time. In packetC, operators follow what you would expect from C99, although there are many special data types that interact in a few interesting ways with the standard operators.
