operator const char*

Why that the function c_str and operator const char* didn't return the same value in this code ?

#include <iostream> usingnamespace std; class MyString { char* buffer; int length; public: MyString(constchar* pChaine); ~MyString(); constchar* c_str()const; operatorconstchar*()const; }; MyString::MyString(constchar* pChaine) { length = strlen(pChaine); buffer =newchar[length + 1]; strcpy(buffer, pChaine); } MyString::~MyString() { if (buffer != NULL) delete[] buffer; length = 0; } constchar* MyString::c_str()const { return buffer; } MyString::operatorconstchar*()const { return buffer; } int main() { MyString s1("Hello"); cout << s1.c_str() << endl; cout << s1 << endl; return 0; }

Return value:

Hello
003207A8 (adress of buffer)

Thanks
