A1058 A+B in Hogwarts (20)（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
AC代码
#include <stdio.h>
int main() {
int a[3], b[3], c[3];
scanf("%d.%d.%d %d.%d.%d", &a[0], &a[1], &a[2], &b[0], &b[1], &b[2]);
int carry = 0;//进位
c[2] = (a[2] + b[2]) % 29;//二号位结果
carry = (a[2] + b[2]) / 29;//进位
c[1] = (a[1] + b[1] + carry) % 17;//一号位结果（加上进位）
carry = (a[1] + b[1] + carry) / 17;//进位
c[0] = a[0] + b[0] + carry;//无限制，不必再处理进位了
printf("%d.%d.%d", c[0], c[1], c[2]);
return 0;
