Có rất nhiều ví dụ sai sót như vậy, nhưng một ví dụ đơn giản là đủ. Giả sử rằng trong một chương trình, bạn có thể so sánh hai con số cho hội tụ, đó là, để xem sự khác biệt giữa hai con số là ít hơn so với một số giá trị định trước | Simpo PDF1 M ergeand SplitPUnregisterecf Version - http www .simpopdf.com Table 3.2 Inspection Error Checklist Summary Part II Control Flow Input Output 1.

Constants passed as arguments Walkthroughs The code walkthrough like the inspection is a set of procedures and error-detection techniques for group code reading. It shares much in common with the inspection process but the procedures are slightly different and a different error-detection technique is employed. Like the inspection the walkthrough is an uninterrupted meeting of one to two hours in duration. The
