Code is corect and should compile. There is no syntax errors. What exactly your promlem is?

[Makambi]

am using code blocks..what compiler dd u use
126 error: no match function for call to 'std::basic_ofstream<char>::basic_ofstream(std::string, cont openmode&)'

[MiiNiPaa]

Settings → Compiler → check have g++ follow C++11 ISO C++ language standard
