You can store all string in an array and using loop you can check. If any string exist then break the loop.

Answer 2

MrDevEzeoke , what you could do additionally is to spell the "keywords" in lower case:

string[] words = {"how", "where", "why", "when", "which"};

then also convert the input to lower case:

string question = Console.ReadLine().ToLower();

This makes it possible to find "Why" as well as "why" or whatever case is used.

Answer 3

MrDevEzeoke

Can Contains accept multiple String?

Answer 4

Or starting from the array of keywords you can combine Any() and Contains(). To use Any() you have to include Linq.

if(Keywords.Any(kw => question.Contains(kw)))

Answer 6

I Am AJ ! No it can't. I guess that answers my question however how would I check for these multiple strings within the inputed question?
