出现此问题是因为您没有检查CurrentNdx确保您没有用完数组.
每次增加它时，都需要检查它是否不超过可用空间.
顺便说一句:不要仅仅发布整个程序:它被称为代码转储，被认为是懒惰而粗鲁的.请以后再发布相关的代码片段.这将帮助我们为您提供帮助，因为我们无需费心查看格式错误的代码即可找到相关部分.

[edit]Code block added, "Treat my content as plain text..." option disabled - OriginalGriff[/edit]
The problem occurs because you have no checking onCurrentNdxto make sure you do not run out of the array.
You need to check that it does not exceed the available space each time you increment it.
BTW: Don''t just post your whole program: it is called a Code Dump and considered lazy and rude. Post just the relevant code fragments in future, please. This helps us to help you as we do not have to wade through your badly formatted code to find the relevant parts.
这篇关于B32assembler代码中的错误的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
