PAT(甲级)渡劫(十八)-A+B in Hogwarts(20)

代码如下：

#include <iostream>
#include <cstdio>
#include <bits/stdc++.h>

using namespace std;

int main(){
    //freopen("in.txt","r",stdin);
    char s1[30],s2[30];
    int a[5],b[5];
    scanf("%s%s",s1,s2);
    char *result = NULL;
    result = strtok(s1,".");
    int cnt1 = 0;
    while(result != NULL){
        a[cnt1++] = atoi(result);
        result = strtok(NULL,".");
    }

    result = NULL;
    result = strtok(s2,".");
    int cnt2 = 0;
    while(result != NULL){
        b[cnt2++] = atoi(result);
        result = strtok(NULL,".");
    }

    int ans,tmp;
    int c[5],cnt3 = 0;
    for(int i = 2 ; i >= 0 ; i--){
        if(i == 2){
            ans = (a[i] + b[i])%29;
            tmp = (a[i]+b[i])/29;
            c[cnt3++] = ans;
        }else if(i == 1){
            ans = (a[i] + b[i] + tmp)%17;
            tmp = (a[i] + b[i] + tmp)/17;
            c[cnt3++] = ans;
        }else{
            ans = (a[i] + b[i] + tmp);
            c[cnt3++] = ans;
        }
    }
    cout<<c[2]<<"."<<c[1]<<"."<<c[0]<<endl;
    return 0;
}

运行结果：
