console with MFC

HEY EVERBODY

I want to use printf() in MFC , i have used but its not give any output, i also used allocconsole but its working well.

I also used following code but its give error that of std is ilegal .
AllocConsole( );

// setup stdout
{
int fd = _open_osfhandle( (long)GetStdHandle( STD_OUTPUT_HANDLE ), 0);
FILE* fp = _fdopen( fd, "w" );

*stdout = *fp;
setvbuf( stdout, NULL, _IONBF, 0 );
}
// setup stdin
{
int fd = _open_osfhandle( (long)GetStdHandle( STD_INPUT_HANDLE ), 0);
FILE* fp = _fdopen( fd, "r" );

*stdin = *fp;
setvbuf( stdin, NULL, _IONBF, 0 );
}

// test stdin & stdout
std::cout << "Console in place. Type a number: ";
/*
int x = 0;
std::cin >> x;

std::cout << "Value read: " << x << std::endl;

// generated code
*/

FreeConsole();
