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:

3.2.1 10.16.27

Sample Output:

14.1.28

#include <iostream>
using namespace std;

int main() {
	int a1, b1, c1, a2, b2, c2, a, b, c;
	scanf("%d.%d.%d %d.%d.%d", &a1, &b1, &c1, &a2, &b2, &c2);
	c = (c1 + c2) % 29;
	b = ((c1 + c2) / 29 + b1 + b2) % 17;
	a = a1 + a2 + ((c1 + c2) / 29 + b1 + b2) / 17;
	cout << a << '.' << b << '.' << c;
	return 0;
