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.

Parameters
    __res_arg Number of characters required.

Exceptions
    std::length_error If __res_arg exceeds max_size().

Resizes the string to the specified number of characters.

Parameters
    __n Number of characters the string should contain.

This function will resize the string to the specified length. If the new size is smaller than the string's current size the string is truncated, otherwise the string is extended and new characters are default-constructed. For basic types such as char, this means setting them to 0.

Parameters
    __n Number of characters the string should contain.
    __c Character to fill any new elements.

This function will resize the string to the specified number of characters. If the number is smaller than the string's current size the string is truncated, otherwise the string is extended and new elements are set to __c.
