A1058. A+B in Hogwarts

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

 #include<cstdio>
 #include<iostream>
 using namespace std;
 int main(){
     long long A[], B[] ,c, c1, c2, c3;
     scanf("%lld.%lld.%lld %lld.%lld.%lld", &A[], &A[], &A[], &B[], &B[], &B[]);
     c = A[] *  *  + A[] *  + A[] + B[] *  *  + B[] *  + B[];
     c1 = c /  / ;
     c2 = (c / ) % ;
     c3 = c % ;
     printf("%lld.%lld.%lld", c1, c2, c3);
     cin >> c;
     return ;
 }

1、十分简单的进制转换题，两种方法，统一换算成最低位的单位求和，再换算。或者按照加法进位来做。注意最高位的取值达到了10^7，若用第一种方法，可能要使用long long存储。

2、long long 型在输入和输出时为%lld。
