PAT甲级——A1058 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], 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 A[3], B[3], C[3], s = 0;
    scanf("%d.%d.%d", &A[0], &A[1], &A[2]);
    scanf("%d.%d.%d", &B[0], &B[1], &B[2]);
    C[2] = (A[2] + B[2] + s) % 29;
    s = (A[2] + B[2] + s) / 29;
    C[1] = (A[1] + B[1] + s) % 17;
    s = (A[1] + B[1] + s) / 17;
    C[0] = A[0] + B[0] + s;
    printf("%d.%d.%d
", C[0], C[1], C[2]);
    return 0;
