Lập trình phòng ngừa
Defensive programming
▪Ý tưởng chính: nếu chương trình (CTC) nhận dữ liệu
vào bị lỗi thì nó vẫn chạy thông, ngay cả khi chương
trình khác cũng nhận dữ liệu đầu vào đó đã bị lỗi.
▪Lập trình phòng ngừa là cách tự bảo vệ chương trình
của mình khỏi
▫các ảnh hưởng tiêu cực của dữ liệu không hợp lệ
▫các rủi ro đến từ các sự kiện tưởng như "không bao giờ"
xảy ra
▫sai lầm của các lập trình viên khác
