Hello, You can use this library to get ip adresses from in the string!
#include "ipparser.h"
if (isIp("my ip is 192.168.1.1"))
{
std::cout << "this is a ipv4" << endl;
}
std::cout << getIp("my ip is 192.168.1.1", "My expression message is this!") << endl;
std::cout << getIp("my ip is 192.168.1.1") << endl;This library works with Regular Expression (RegEx), You can find expression from here;
([0-9]{1,3}[\.]){3}[0-9]{1,3}
The main point was learning the RegEx in C++.
