Can any one tell me the difference between .npos and .length in the c++?

#1

if (ss.find(out) !=ss.npos )
{
cout << ss << endl;
}

what happens if I use ss.length In place of ss.npos?

hello @sahilkhan2312000131

it will not work.

ss.npos is a constant whoose value is -1.

and find function return -1 ,if it does not find the string so use ss.npos only
