Lexicographically compare the substring of this string of the specified lhsNumChars length starting at the specified lhsPosition (or the suffix of this string starting at lhsPosition if lhsPosition + lhsNumChars > length()) with the substring of the specified other string of the optionally specified otherNumChars length starting at the specified otherPosition (or the suffix of other starting at otherPosition if otherPosition + otherNumChars > other.length()). If numChars is not specified, npos is used. Return a negative value if the indicated substring of this string is less than the indicated substring of other, a positive value if it is greater than the indicated substring of other, and 0 in case of equality. CHAR_TRAITS::lt is used to compare characters. Throw out_of_range if lhsPosition > length() or otherPosition > other.length(). See {Lexicographical Comparisons}.
