That wouldn't make sense, because you're trying to multiply a type with a value.

Maybe you meant :

        sizeof(int) * 3

?

Although something like this should work...

sizeof ( 3 * 6 );

...since the result of 3 * 6 (both of implicit type int) is of type int thus the sizeof will return the size of the result type, which is an int.
