[pso] Intrebare (masina big-endian)

[mE]

int a[] = {0x12345678, 0x22334455};
memdump arata asa:
0x78 0x56 0x34 0x12 0x55 0x44 0x33 0x22

da?
eu stiam ca bigendian se refera la asezarea byteurile intr-un numar
intreg (gen int32_t) si nu intr-un sir. pentru siruri ordinea nu
trebuie sa se schimbe.

daca ai facut ceva de genul:
int a = 45354;
char *str = (int*)&a; s-ar putea sa ai surprize de genul celor de mai
sus, altfel nu vad cum ai obtinut 'd' in loc de 'a'.

oricum, e posibil sa gresesc eu...
