can you please explain what has been done in line 16 to line 20
General code doubt
hello @sneha23
in line 16, we are finding index of string f in string searchIn[x].
if the string is present in serachIn[x] (as substring) then we are simply printing it.
if string f is not present in searchIn[x] then in that case find function will return npos constant which is predefined in c++. so we using that value as indicator to detect wheter string f is present or not in searchin[x]
