1058. A+B in Hogwarts (20)-PAT甲级真题

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

题目大意：17个Sickle对换一个Galleon，29个Knut对换一个Sickle。根据Galleon.Sickle.Knut的方式相加A和B
分析：像相加算术一样从后往前按位相加，处理好进位～

#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;
    b = b1 + b2 + c / 29; c = c % 29;
    a = a1 + a2 + b / 17; b = b % 17;
    printf("%d.%d.%d\n", a, b, c);
    return 0;
}

#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;

b = b1 + b2 + c / 29; c = c % 29;

a = a1 + a2 + b / 17; b = b % 17;

printf("%d.%d.%d\n", a, b, c);

return 0;
