📃 함수 오버로딩으로 swap 하기

#include <iostream>
using namespace std;

int main()
{
	int num1 = 30, num2 = 40;
	swap(num1, num2);
	cout << num1 << ' ' << num2 << endl;

	char char1 = 'A', char2 = 'B';
	swap(char1, char2);
	cout << char1 << " " << char2 << endl;

	double Dob1 = 3.14, Dob2 = 1.222;
	swap(Dob1, Dob2);
	cout << Dob1 << " " << Dob2 << endl;
 	return 0;
}
