Integer < 0, 0, or > 0.
Form the substring of this string from the __n1 characters starting at __pos1. Form the substring of
__str from the __n2 characters starting at __pos2. Returns an integer < 0 if this substring is ordered
before the substring of __str, 0 if their values are equivalent, or > 0 if this substring is ordered
after the substring of __str. Determines the effective length rlen of the strings to compare as the
smallest of the lengths of the substrings. The function then compares the two strings by calling
traits::compare(substring.data(),str.substr(pos2,n2).data(),rlen). If the result of the comparison is
nonzero returns it, otherwise the shorter one is ordered first.

Attempt to preallocate enough memory for specified number of characters.
Parameters
__res_arg Number of characters required.
Exceptions
std::length_error If __res_arg exceeds max_size().
This function attempts to reserve enough memory for the string to hold the specified number of
characters. If the number requested is more than max_size(), length_error is thrown.
The advantage of this function is that if optimal code is a necessity and the user can determine the
string length that will be required, the user can reserve the memory in advance, and thus prevent a
possible reallocation of memory and copying of string data.
