if you know the start and end positions in string from where to begin and end the search. For example –
string s = StringStringString
|S |t |r |i |n |g |S |t |r |i |n |g |S |t |r |i |n |g
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
How would you find “tr” in the string specifying the the position to begin search is at index 6 and the position to end the search is index 9.
I’m trying a set a limit of search so it wouldn’t go beyond it.
If you really want to limit the length of the sequence that gets traversed (presumably because the string is very long compared to the interesting region), use
std::searchand pass it the corresponding iterators into the string.
