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

__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

Replace range of characters with multiple characters.
Parameters
__i1 Iterator referencing start of range to replace.
__i2 Iterator referencing end of range to replace.
__n Number of characters to insert.
__c Character to insert.
Returns
Reference to this string.
Exceptions
std::length_error If new length exceeds max_size().
Removes the characters in the range [__i1,__i2). In place, __n copies of __c are inserted. If the length
of result exceeds max_size(), length_error is thrown. The value of the string doesn't change if an error
is thrown.

Replace range of characters with string_view.
Parameters

Replace characters with value from another string.
Parameters
__pos Index of first character to replace.
__n Number of characters to be replaced.
__str String to insert.
Returns
Reference to this string.
Exceptions
std::out_of_range If pos is beyond the end of this string.
std::length_error If new length exceeds max_size().
Removes the characters in the range [__pos,__pos+__n) from this string. In place, the value of __str is
inserted. If __pos is beyond end of string, out_of_range is thrown. If the length of the result exceeds
max_size(), length_error is thrown. The value of the string doesn't change if an error is thrown.

Replace range of characters with string_view.
Parameters
__pos1 The position to replace at.
__n1 The number of characters to replace.
__svt The object convertible to string_view to insert from.
__pos2 The position in the string_view to insert from.

Replace characters with value from another string.
Parameters
__pos1 Index of first character to replace.
__n1 Number of characters to be replaced.
__str String to insert.
__pos2 Index of first character of str to use.
__n2 Number of characters from str to use.
Returns
Reference to this string.
Exceptions
std::out_of_range If __pos1 > size() or __pos2 > __str.size().
std::length_error If new length exceeds max_size().
Removes the characters in the range [__pos1,__pos1 + n) from this string. In place, the value of __str is
inserted. If __pos is beyond end of string, out_of_range is thrown. If the length of the result exceeds
max_size(), length_error is thrown. The value of the string doesn't change if an error is thrown.

template<typename _CharT , typename _Traits = std::char_traits<_CharT>, typename _Allocator =

template<typename _CharT , typename _Traits = std::char_traits<_CharT>, typename _Allocator =
std::allocator<_CharT>> void std::basic_string< _CharT, _Traits, _Alloc >::reserve (size_type __res_arg)
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.

Find last position of a string_view.
Parameters
__svt The object convertible to string_view to locate.
__pos Index of character to search back from (default end).
Returns
Index of start of last occurrence.

[inline], [noexcept], [inherited]
Find last position of a string.
Parameters
__str String to locate.
__pos Index of character to search back from (default end).
Returns
Index of start of last occurrence.
Starting from __pos, searches backward for value of __str within this string. If found, returns the index
where it begins. If not found, returns npos.
