Find_first_of and find_first_not_of

Question

Can someone explain how these two functions work in key value pair when handling strings? Provide a couple of examples would be great. Thanksss

Answer 1

Can you explain a bit more this key-value pair case? to my understanding, those methods are used to find a character that does/not exist in a character sequence. It would be nice if you can post your code involving these methods so people can see and offer suggestions : )
