each.with_index

Hello,

I have an array :-

a = [1, 2, 3, 4, 5]

I have 13 objects with sequence. I want to assign a’s value to these objects which will be repeated.

so after every 5 objects, these a’s value will be assigned & will be repeated.

a.each.with_index do |col, col_index|

Some code here.

// How should I again assign the col_index to ‘0’ again, so that I can repeat those values & save values to the objects?

end

I am able to assign first 5 objects.

Thanks,

Avinash

Take a look at the % (modulus) operator.

As Dave answered, modulus is your answer -

a.each_with_index do |obj, idx| if (idx % 5 == 0) # this is your starting point for each group of 5

end

do other stuff here…
