Probably just a blackout

I have two pieces of code supposed to do the same thing (read an unsigned 32-bit big-endian integer from a memory stream):

Code:

---

return dword(
          ((static_cast<dword>(*source++)) << 24)
        | ((static_cast<dword>(*source++)) << 16)
        | ((static_cast<dword>(*source++)) <<  8)
        | ((static_cast<dword>(*source++))      )
        );

---

Code:

---

dword d1, d2, d3, d4;
d1 = *source++;
d2 = *source++;
d3 = *source++;
d4 = *source++;
dword ret = (d1 << 24) | (d2 << 16) | (d3 << 8) | d4;
return ret;

---

However the second one works and the first always returns 0. Why?

as a relative newb to C++, I doubt I'll be helping.

Is it anything to do with "*source++" being "++*source"?

No? ok.

No. It's not the same, and this piece of code is the same for both.

The increment seems to be done after the statement.

But what are the parenthese doing there then?

But you could be right...

I've tested it, the first byte is dereferenced each time

damn

ok, I'll experiment with it
