PAT (Advanced Level) Practice 1058 A+B in Hogwarts（20分）

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 $[0,10^7]$, 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

代码

#include <cstdio>

struct m {
    int g, s, k;
};

int main() {
    m a, b;

    scanf("%d.%d.%d %d.%d.%d",
          &a.g, &a.s, &a.k,
          &b.g, &b.s, &b.k);

    a.g += b.g;
    a.s += b.s;
    a.k += b.k;

    if (a.k >= 29) {
        a.s += a.k / 29;
        a.k %= 29;
    }

    if (a.s >= 17) {
        a.g += a.s / 17;
        a.s %= 17;
    }

    printf("%d.%d.%d", a.g, a.s, a.k);
}
