    getFiles(filePath, files);

    char str[30];

    for (size_t i = 0; i < size; i++)

    }
    return 0;
}

运行结果及报错内容

我的解决思路

参考了网上vector subscript out of range的方法
例如
https://blog.csdn.net/qq_15505637/article/details/52995408?utm_medium=distribute.pc_relevant.none-task-blog-2~default~baidujs_title~default-1.pc_relevant_paycolumn_v2&spm=1001.2101.3001.4242.2&utm_relevant_index=4

已经有这行代码

files.push_back(p.assign(path).append("\").append(fileinfo.name));

访问越界了，学会自己调试
