Gửi bạn Trần Trung và các bạn sv CNTT cần quan tâm, chương trình mô phỏng Excel viết bằng C++


// Chuong trinh mo phong Excel bang C++
// Chuong trinh co thuc hien xu ly mot so bieu thuc tuong tu trong Excel
// Bai nay la mot bai tap lon cua sinh vien Khoa Cong nghe DHQG HN thuc hien
// Sinh vien Ha Anh Tu suu tam

Huong dan su dung:
+ Nhap du lieu: Bam Enter
+ Ket thuc chuong trinh: Alt+Q
+ Bam Alt+phim nong: Chon lenh tren thuc don
+ Cac kieu du lieu:
. Kieu chuoi: Hien thi duoc can trai
. Kieu so: Hien thi duoc can phai
. Cong thuc: duoc bat dau boi dau =
+ Cac ham duoc su dung:
. SUM(gia tri, vung o, ham...): tinh tong
. MAX(...): Tinh gia tri lon nhat
. MIN(...): Tinh gia tri nho nhat
. SIN(bieu thuc): Tinh sin
. COS(...): tinh cos
. ATAN(...): tinh Arctan
+ He thong tu tinh toan lai khi co su thay doi du lieu tren cac o
Chuong trinh su dung dem dia nen khi tinh toan lai,
voi toc do may cham thi toc do tinh tuong doi cham (it nhat cau hinh P166 16M RAM)
+ Bao loi neu cong thuc nhap sai
+ Chuong trinh cho phep doc va luu tru du lieu tren dia
+ Khi thuc hien, neu dang nhap du lieu thi khong dieu
khien di chuyen hoac chon lenh hoac ket thuc
* Luu y: + Khong duoc goi de quy dia chi o trong cong thuc
vi su de quy do khong co dieu kien dung, se gay thieu bo nho
+ Chuong trinh su dung o dia ao C: de lam bo dem cho mang gia tri
(khong su dung o dia hien thoi vi la o mang nen toc do doc cham)
+ Doi khi cong thuc tinh hien ket qua sai, khong phai do chuong trinh
ma do toc do may cham nen hien thi mot gia tri khong dung, can cho mot luc
