12 February 2008 | LINuX For you | www. openITis. com c m y k Insight hen can we write highly efficient code? It is when we understand how the underlying machine works and make best use of that knowledge. One well-known way to write highly efficient code is to write code in assembly. There are many disadvantages with this; for example, we cannot port the programs easily, it is difficult to maintain the code, etc. So, we need to look W for alternatives to write efficient code. We can write in low-level programming languages like C to get write code, whose efficiency is often comparable to the equivalent code written in assembly. For this reason, C is often referred as a ‘high-level assembler’. In this article, we’ll look at various programming constructs from the perspective of efficiency. We’ll consider general machine architecture for illustration; and for specific How many programmers can actually write assembly programs? With the rising popularity of high-level languages (lik Less
