使用C ++对ipv6地址进行比较操作 [英] Comparison operations on ipv6 address using C++

问题描述

hi
由于IPV6地址有16个字节，并且它们没有数据类型存储在c ++中，
i希望存储IPV6地址，并在IPv6地址和
之间做一些比较请让我知道如何做

hi As IPV6 address has 16 bytes and their is no data type to store it in c++, i wanted to store the IPV6 address, and do some comparisions between to IPv6 address, please let me know how to do it

推荐答案

您可以将它们存储为 unsigned char s。像 unsigned char ipv6 [16]; 例如。然后你可以使用任何数组比较算法进行比较。使用 char * 算法不是一个选项，因为您的ipv6地址的某些字节可能是 0x00 基于字符串的算法的字符串结束字符。

You can store those as plain arrays of unsigned chars as you would do in C. Like unsigned char ipv6[16]; for example. You could then compare them using any array comparison algorithm out there. Using char* algorithms wouldn't be an option as some bytes of your ipv6 addresses could be 0x00 and thus interpreted as a string ending character by string-based algorithms.
