Thread: How I can search a string and identify where words begin and end?

Please, i would like to know how to search a string and identify where words begin and end.

for example: want to search "how" from the string "Hello how are you?"
However, I want the index number in the array from where the find starts i.e 7 as "how" starts from 7 position
in "Hello how are you?" string.


Thanks a lot
