Reset C int array to zero : the fastest way?

Of course you can also do whole word matches with regex using the "\b" token.
The performance of these and Kenny's solution are going to depend on several factors, such as how long the word list and phrase string are, and how often they change. If performance is not an issue then go for the si...
