If you are a fan of Harry Potter, you would know the world of magic has its own currency system — as Hagrid explained it to Harry, “Seventeen silver Sickles to a Galleon and twenty-nine Knuts to a Sickle, it’s easy enough.” Your job is to write a program to compute A+B where A and B are given in the standard form of “Galleon.Sickle.Knut” (Galleon is an integer in [0, 10⁷], Sickle is an integer in [0, 17), and Knut is an integer in [0, 29)).
Input Specification:
Each input file contains one test case which occupies a line with A and B in the standard form, separated by one space.
Output Specification:
For each test case you should output the sum of A and B in one line, with the same format as the input.
Sample Input:

3.2.1 10.16.27

Sample Output:

14.1.28

===========================
很简单的问题，就不多写了~代码也很粗糙，嘿嘿

#include 
using namespace std;
int main()
{
	long galleon[2] = {0,0};
	int sickle[2] = {0,0}, knut[2] = {0,0};
	scanf("%ld.%d.%d", &galleon, &sickle, &knut);
	scanf("%ld.%d.%d", &galleon[1], &sickle[1], &knut[1]);
	long G = 0;
	int  S=0, K=0;
	K = knut[0] + knut[1];
	while(K > 28)
	{
		K -= 29;
		S ++;
	}
	S += sickle[0];
	S += sickle[1];
	while(S > 16)
	{
		S -= 17;
		G ++;
	}
	G += galleon[0];
	G += galleon[1];
	printf("%ld.%d.%d",G, S, K);
	return 0;
}
