Question

I find the multiple nested for loops very
challenging to deal with ,please give some typical example of dealing with it

Answer 1

Nested loops are mostly used in handling 2D arrays.

Answer 2

I had only a couple hours to get a enormous data table made and out to production. I got a raw ungrouped data stream. Fastest and ugliest way to do it was loop through the data once to create a 6 layer deep set of arrays doing multiple groupings and then have 6 nested for loops to build the interactive tables. Was ugly but it works.

Nested for loops can be a pain to read and keep track of so it is important to use variable names that have meaning on the loop they are iterating over.
