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

思路：

设置三组变量，根据加法运算从后往前运算，注意进位。

 

#include <iostream>
using namespace std;
int main() {
    int a, b, c, m, n, t, x, y, z;//分别表示A B和A+B
    scanf("%d.%d.%d %d.%d.%d", &a, &b, &c, &m, &n, &t);
    z = (c + t) % 29;
    y = (b + n + (c + t) / 29) % 17;
    x = a + m + (b + n + (c + t) / 29) / 17;
    printf("%d.%d.%d", x, y, z);
    return 0;
}
