Compare to a string.

Parameters

__str String to compare against.

Returns

Integer < 0, 0, or > 0.

Returns an integer < 0 if this string is ordered before __str, 0 if their values are equivalent, or > 0 if this string is ordered after __str. Determines the effective length rlen of the strings to compare as the smallest of size() and str.size(). The function then compares the two strings by calling traits::compare(data(), str.data(),rlen). If the result of the comparison is nonzero returns it, otherwise the shorter one is ordered first.

Compare substring to a string.

Parameters

__pos Index of first character of substring.
__n Number of characters in substring.
__str String to compare against.

Returns

Integer < 0, 0, or > 0.

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

Returns

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.

template<typename _CharT , typename _Traits = std::char_traits<_CharT>, typename _Allocator = std::allocator<_CharT>> void std::basic_string< _CharT, _Traits, _Alloc >::reserve

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.
