string 문자열 붙여넣기하는 방법

#include <iostream>  
#include <string>  
using namespace std;

int main()
{
	string base = "hello world";

	if (base.find("world") != string::npos)
	{
		cout << "find";  
	}

	string s1("Hello");
	string s2(" world");
	s1 += " wow! ";
	s2 += " ^^ ";
	cout << s1 << endl;
	cout << s2 << endl;

	cout << s1.append(s2);

	return 0;
}
