Code C\C++: Ví dụ 2, xử lý cấu trúc (struct) - 14-01-13

/* vi du 2 - struct
Viet cac ham:
1. Nhap vao thong tin 1 nhan vien IT, gom:
- Ho ten
- Tuoi
- Vi tri lam viec
- He so luong
- So nam cong tac
2. In thong tin nhan vien vua nhap
3. Tinh luong cho nhan vien
luong=he so luong * luong co ban + phu cap
trong do:   phu cap = 1,2 luong co ban neu so nam cong tac > 3
nguoc lai phu cap = 1 luong co ban.
4. Tinh thue thu nhap ma nhan vien phai tra.
neu luong>5.000.000 thi thue 10% luong
nguoc lai thue =0.
