Salut Ianule,

Mai, la prima intrebare. N-are imprtanta extensia '.dat'. Important este ce program a creat acel fisier. Fisierul poate sa fie de orice fel, "dat' e un nume ad-hoc pe care multe programe il folosesc, cu intelesul ca acolo se afla niste date.

La a doua intrebare, pot sa-ti spun ca nu exista asa ceva. Un fisier in cod sursa (.cpp, .c, .pas) este compilat in tr-un format obiect si apoi se foloseste un link editor (editor de legaturi) in functie de sistemul de operare, care va genera fisierul executabil. Un compilator modern include de fapt un compilator si un linkeditor.
Odata generat, un fisier executabil nu poate fi decat in cel mai bun caz, dezasamblat, adica va fi decompilat in limbaj de asamblare.
Sunt destul de multe programe de acest fel, folosite de crackeri, cum ar fi Olly, Ida, etc.. Acest proces se numeste reverse engineering, si necesita solide cunostinte de limbaj de asamblare.

Sper ca ti-am fost de folos
