Last week I took Brainbench test. There there are couple of questions on code optimization. In place of "for" loop what loop construct can we use? Actually I am new to the are of performance tuning. Can any one help me with some basic ideas or thumb rules which I can follow in my day-today programming?
Thanks in advance

In place of the for loop, you can use 'while', but this is not a performance issue. All loops are functionally identical and can be converted between themselves.
In terms of basic rules-of-thumb for programming from the view of performance, you should code without really considering performance. Performance should be considered at the analysis/design stages, and <em>after</em> the implementation has become functional. Then the application should be profiled to find the bottlenecks, and those bottlenecks removed.
