STL - string

构造函数
string();
string( const string& s );
string( size_type length, const char& ch );
string( const char* str );
string( const char* str, size_type length );
string( const string& str, size_type index, size_type length );
string( input_iterator start, input_iterator end );
~string();

运算符
[], =, ==, !=, >, >=, <, <=, +, <<, >>
两个string相等：所有相同位置的元素相等
两个string大小比较：按照词典规则

迭代器
iterator begin();
iterator end();
reverse_iterator rbegin();
reverse_iterator rend();

访问
TYPE& at( size_type loc );

void insert( iterator i, size_type num, const char& ch );
void insert( iterator i, iterator start, iterator end );

void push_back( const TYPE& val );
istream& getline( istream& is, string& s, char delimiter = '\n' );

移除
iterator erase( iterator loc );
iterator erase( iterator start, iterator end );
string& erase( size_type index = 0, size_type num = npos );
void clear();

比较
int compare( const string& str );
int compare( const char* str );
