The result of an n++ operation is the original value. 

f2 = f1++;  // f2 = f1 + 1"

please, menchar ! wake up, drink a cup of coffee or get some sleep ! the ++ operator increments in place: a++ <= > a += 1 <=> a = a + 1
or we would write our loops as "for ( i = 0; i < value; i = i++ )", which obviously we don't.

Dummy -

The general case of postfix and prefix operators (or any expression for that matter) when evaluated in the C programming language is to discard the result.

The ++ and -- operators are an exception, in that they're applied to lvalues only.

I like Starbucks if you're buying.
