I'm trying to find the index of a substring in another string, using find(), but getting a junk value and not std::npos if the substring is not there.
This is the Code:
string output1 = "abcd";
cout << output.find("gf") << endl;
And this is the output:
18446744073709551615
can this behaviour be prevented? is there another way to find the substring?
(actually i only need to find if the substring is contained)
Thank you
What it return is size_t
of npos of your string because it can't find your char or text. you can do this instead:
std::size_t found = str.find("findme");
if (found != std::string::npos)
std:cout << found << std::endl;
else
std::cout << "String not found" << std::endl // If not found
