What's wrong with this C declaration Code?

HANDLE wHnd;    // Handle to write to the console.
HANDLE rHnd;    // Handle to read from the console.

int _tmain(int argc, _TCHAR* argv[]) {

    // Set up the handles for reading/writing:
    wHnd = GetStdHandle(STD_OUTPUT_HANDLE);
    rHnd = GetStdHandle(STD_INPUT_HANDLE);

    // Change the window title:
    SetConsoleTitle(TEXT("Win32 Console Control Demo"));

    // Set up the required window size:
    SMALL_RECT windowSize = {0, 0, 79, 49};

    // Change the console window size:
    SetConsoleWindowInfo(wHnd, TRUE, &windowSize);

}

Some errors like this are reported:

'SMALL_RECT' : illegal use of this type as an expression  
missing ';' before identifier 'windowSize'

You are using the MS C compiler which only supports the now ancient C90 standard. All your variables must be declared at the top of the function body.

int _tmain(int argc, _TCHAR* argv[])
{    
    // Set up the required window size:
    SMALL_RECT windowSize = {0, 0, 79, 49};

    // Set up the handles for reading/writing:
    wHnd = GetStdHandle(STD_OUTPUT_HANDLE);
    rHnd = GetStdHandle(STD_INPUT_HANDLE);

    // Change the window title:
    SetConsoleTitle(TEXT("Win32 Console Control Demo"));

    // Change the console window size:
    SetConsoleWindowInfo(wHnd, TRUE, &windowSize);
}

Painful, isn't it?!
