PAT 1058. A+B in Hogwarts (20)

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思路：按进数位取余，保存进位到下位运算。
#include <cstdio>int main(){int a[3], b[3];scanf("%d.%d.%d", &a[0], &a[1], &a[2]);scanf("%d.%d.%d", &b[0], &b[1], &b[2]);int t1, t2;   //保存进位t1 = (a[2] + b[2]) / 29;  //按范围操作即可，进位除，结果余a[2] = (a[2]+b[2]) % 29;t2 =  (a[1] + b[1] + t1) / 17;a[1] = (a[1]+b[1] + t1) % 17;a[0] = (a[0]+b[0] + t2);printf("%d.%d.%d\n", a[0], a[1], a[2]);  return 0;}
