PAT-A 真题 – 1058 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

这道题很简单，不做详细解释。

#include <stdio.h>

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]);
  for(int i = 0; i < 3; i++) a[i] += b[i];
  a[1] += (a[2] / 29), a[2] %= 29;
  a[0] += (a[1] / 17), a[1] %= 17;
  printf("%d.%d.%d\n", a[0], a[1], a[2]);
  return 0;
