<locale>

ctype

protected member function
<locale>

std::ctype::~ctype

~ctype();
ctype destructor
Destroy the ctype object.

这是一个受保护的析构函数：程序不应直接构造此类对象。

此析构函数因继承而成为虚函数（locale::facet 的析构函数是虚函数）。

Specialization for ctype<char>

On the char specialization, the destructor calls delete[] table() if it was constructed with explicit first and second arguments (different from their default values).
