避免“缓冲区溢出"C6386 警告 [英] Avoiding 'Buffer Overrun' C6386 warning

问题描述

在我的代码中，我使用了一个包含 10 个对象的数组 xyz.当我尝试使用如下所示的 unsigned int 索引访问数组元素时:xyz[level]，我得到 '缓冲区溢出' 警告.从逻辑上讲，我很确定该级别不会超过 10.如何避免此警告?

In my code, I am using an array xyz of 10 objects. When I am trying to access an element of the array using an unsigned int index like this: xyz[level], I get 'Buffer overrun' warning. Logically, I am pretty sure that level won't exceed 10. How to avoid this warning?

推荐答案

我可能在这里教我祖母吸鸡蛋，但请记住，对于大小为 10 的数组，级别不会超过 10"是错误的:

I'm probably teaching my grandmother to suck eggs here, but do remember that "level won't exceed 10" is wrong for an array of size 10:

char a[10];
a[10] = '\0';  // Bug, and "Buffer Overrun" warning.
