1058. A+B in Hogwarts (20)-PAT甲级

题目：

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

解答：

#include<cstdio> 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]); c[0]=a[0]+b[0]; c[1]=a[1]+b[1]; c[2]=a[2]+b[2]; if(c[2]>=29){ c[2]=c[2]-29; c[1]++; } if(c[1]>=17){ c[1]=c[1]-17; c[0]++; } printf("%d.%d.%d",c[0],c[1],c[2]); return 0; }
