Rubbish Character When Return ?

[hentaiw]

	string result = str.substr( find_array1 + 1,find_array2 - 1 ).c_str();

	cout << result.c_str();

	return result.c_str();
}

My function const char* get_value_cstr(fstream &fin) takes fstream as you can see.The cout << here produces a legit string. (means all readable).

but I return the same thing as right-operand of cout <<

and call it outside the function

cout << get_value_cstr(fin);

It justs shows rubbish characters,I don't know why.

That's because the c_str is invalidated when you delete the std::string result.
