Should Nested for loops be avoided?

Question

Some times, nested for loops produce desired output.
But, it looks odd when nested for and if we're used.

Answer 1

You can't really prevent nesting and therefore indentation.

I feel that 5 or 6 levels should be the limit.

If you move further to the right, you should think about restructuring the code somewhat, for example using functions.
