What is an ideal variable naming convention for loop variables? [closed]

Answer 1

1) For normal old style small loops - i, j, k - If you need more than 3 level nested loops, this means that either the algorithm is very specific and complex, or you should consider refactoring the code.

Java Example:

for(int i = 0; i < ElementsList.size(); i++) {
  Element element = ElementsList.get(i);
  someProcessing(element);
  ....
}

2) For the new style java loops like for(Element element: ElementsList) it is better to use normal meanigful name

Java Example:

for(Element element: ElementsList) {
  someProcessing(element);
  ....
}

3) If it is possible with the language you use, convert the loop to use iterator
