for loops in Ruby

Expand Post »

I am trying to search through a string to find the number of occurences of a substring. I am doing this for all the strings in an array of strings. I only have figured out the while loops so far. How can I traverse through an array of strings using a for loop?

Re: for loops in Ruby

You don't need to use a loop if you take advantage of the API. If you take the length of the array returned "scanning" for your substring with String#scan, you will have number of occurrences of that substring.
