PAT-A-1058-A+B in Hogwarts

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:

1	3.2.1 10.16.27

Sample Output:

14.1.28

Code

#include <iostream>

using namespace std;

int main(){
	//1：17  1：29
	int galleon,sickle,knut,_galleon,_sickle,_knut;
	scanf("%d.%d.%d %d.%d.%d.",&galleon,&sickle,&knut,&_galleon,&_sickle,&_knut);

    int g,s,h;
    int carry=0;//进位
    h=(knut+_knut)%29;
    carry=(knut+_knut)/29;
    s=(sickle+_sickle+carry)%17;
    carry=(sickle+_sickle+carry)/17;
    g=galleon+_galleon+carry;   

    printf("%d.%d.%lld",g,s,h);
	return 0;
