各位老师，网上找到一篇C++源码，编译出现如下错误，是啥原因呢？

} 兄弟，写入错误无非就是数组越界。调试检查一下你Tzm数组里面的值是不是都小于next数组的大小就得了 Tzm 数据有问题 导致Tzm或者next越界 本帖最后由 mac52pojie 于 2022-4-22 09:35 编辑
num = Tzm;
num = Tzm;
这两句就应该报错了吧，这里已经数组越界了。
你截图的地方应该也是数组越界，你调试的时候可以看到下标应该大于260了。 mac52pojie 发表于 2022-4-22 09:33
num = Tzm;
num = Tzm;
老师，经过调试这个地方还真没有问题？ JuncoJet 发表于 2022-4-22 09:23

老师，如何修改呢？ VS2022 windows sdk 10.0.20348 直接编译运行成功，没有错误。 ★〓★〓★ 发表于 2022-4-22 09:45

老师，多试几次， jtwc 发表于 2022-4-22 09:48
老师，多试几次，
试了很多次了，没有崩溃，只不过搜不到数据而已，结果都是0 WORD TzmLength = strlen(Tzm) / 3 + 1;--->WORD TzmLength = (strlen(Tzm) + 1) / 3;
