Question

a. Realizati o implementare in C a unui tip abstract de date pentru numere complexe. Implementarea va
contine urmatoarele operatii: construirea unui numar complex din partea reala si partea imaginara, suma a
doua numere complexe, diferenta a doua numere complexe, conjugatul unui numar complex, produsul a
doua numere complexe, modulul unui numar complex.
