string::replace

string (1)	string& replace (size_t pos, size_t len, const string& str); string& replace (const_iterator i1, const_iterator i2, const string& str);
substring (2)	string& replace (size_t pos, size_t len, const string& str, size_t subpos, size_t sublen);
c-string (3)	string& replace (size_t pos, size_t len, const char* s); string& replace (const_iterator i1, const_iterator i2, const char* s);
buffer (4)	string& replace (size_t pos, size_t len, const char* s, size_t n); string& replace (const_iterator i1, const_iterator i2, const char* s, size_t n);
fill (5)	string& replace (size_t pos, size_t len, size_t n, char c); string& replace (const_iterator i1, const_iterator i2, size_t n, char c);
range (6)	template <class InputIterator> string& replace (const_iterator i1, const_iterator i2, InputIterator first, InputIterator last);
initializer list (7)	string& replace (const_iterator i1, const_iterator i2, initializer_list<char> il);
