Thread: Return 4 Values

How can I return 4 values???

Code:

#include <iostream>
using namespace std;


double encrypt(int number)
{
	int digit1, digit2, digit3, digit4, encrypt1, encrypt2, encrypt3, encrypt4;
	
	digit4 = number % 10;
	digit3 = ((number % 100) - digit4)/10;
	digit2 = ((number % 1000) - digit3)/100;
	digit1 = ((number - number % 1000))/1000;
	
	encrypt1 = (digit3 + 7)%10;	
	encrypt2 = (digit4 + 7)%10;
	encrypt3 = (digit1 + 7)%10;
	encrypt4 = (digit2 + 7)%10;

}
int main()
{
	int num;

cin>>num;
cout<<encrypt(num);

}
