here is the problem in a different form:


somebody did this code to me:

int varint;
unsigned short varshort;


varint = varshort <<16

how is the order of my bytes in an intel PC memory after this?

varint was undefined
varshort was for example: 56 7F, then 7F is MSB and 56 is LSB (right?).

is varint now :

| starting address
v
56 7F 00 00  (solution A) or
00 00 56 7F  (solution B) or
7F 56 00 00  (solution C) or
00 00 7F 56  (solution D) ????????

I need to know, but everything is turning in my haed.
Cheers
