Best way to find a substring in a string

Question

I have a problem where I am trying to search for a substring in string. That substring may or may not be in the string.

str = \"hello how are you?\"
substr =         


        

Answer 1

In Ruby, use the String#include? method:

str = "hello how are you?"
substr = "how are"
str.include? substr 

which returns true.
