following code is supposed to output 1, but in my vs2005, the output is 0. if i change the "ends_with(str, sz)" into "ends_with(str, string(sz))", the output is correct. i wonder why. is there any difference between these two statement? thanks. // boosttest.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include <boost/algorithm/string.hpp> #include <string> #include <iostream> using namespace boost; using namespace std; int _tmain(int argc, _TCHAR* argv[]) { char sz[1024] = "test.bat"; string str("C:\\test.bat"); cout << ends_with(str, sz) << endl; return 0; } -- Best Regards, Leo Jay
