获取本地计算机的IP地址 [英] Get the IP Address of local computer

问题描述

在C ++中，获取本地计算机的IP地址和子网掩码最简单的方法是什么？

In C++, what's the easiest way to get the local computer's IP address and subnet mask?

我想要能够检测本地计算机的IP地址本地网络。在我的特殊情况下，我有一个网络的子网掩码为255.255.255.0，我的计算机的IP地址是192.168.0.5。我需要获得这两个值以编程方式为了发送广播消息到我的网络（在形式192.168.0.255，对于我的特殊情况）

I want to be able to detect the local machine's IP address in my local network. In my particular case, I have a network with a subnet mask of 255.255.255.0 and my computer's IP address is 192.168.0.5. I need to get these had two values programmatically in order to send a broadcast message to my network (in the form 192.168.0.255, for my particular case)

编辑：多答案没有给出我预期的结果，因为我有两个不同的网络IP。 Torial 的代码做了伎俩（它给了我两个IP地址）。谢谢。

Many answers were not giving the results I expected because I had two different network IP's. Torial's code did the trick (it gave me both IP addresses). Thanks.

编辑2：感谢

Edit 2: Thanks to Brian R. Bondy for the info about the subnet mask.
