Efficient programs come from efficient algorithms. You'd best search for material on algorithms.

    OTOH, "Data dominates. If you've chosen the right data structures and organized things well, the algorithms will almost always be selfevident. Data structures, not algorithms, are central to programming." (Rob Pike Notes on Programming in C)

    As for the OP, "efficient" is a buzzword. Make your programming simple, concise, clear, and correct. For some simple guidelines, try that URL I pasted above, it's the best article about programming practices I know.

      I agree. If it's a straightforward task as it usually is, efficiency shouldn't be a concern. Efficiency is therefore only relevant in the rare cases where there are very demanding needs. That's when you need to worry about your algorithms.

      Rob Pike knows his classics:

      Show me your flowchart and conceal your tables, and I shall continue to be mystified. Show me your tables, and I won't usually need your flowchart; it'll be obvious. -- Fred Brooks, The Mythical Man-Month

      He wrote that in 1975. It's still just as true today.
