nowm = 0 savem = 0 for i in range(1,13): tmp = int(input()) nowm += 300 if tmp > nowm: print("-{}".format(i)) exit() else: nowm -= tmp savem += (nowm // 100) nowm %= 100 nowm += savem * 120 print(nowm)python 就是简洁

【分析】
此题考查的是模拟:
1）框架
int main()
{
int 定义：结余，预算，存款；
for (从1月~12月)
{
输入预算；
得出本月结余并存款；
当结余出现负数时：
}
输出总的攒钱数；
return 0;
}
2)运行过程当中（样例），可能会输入一半就输出-7了，很正常。若想全部输出，可以利用文件的输入与输出，这里介绍一下文件的处理方法：
[注意：双斜线中的内容]
#include <cstdio> //文件所用到的头文件cstdio
using namespace std;
int main()
{
freopen("a+b=c.in","r",stdin); //将输入文件开
freopen("a+b=c.out","w",stdout);//将输出文件开
int a,b,c;
scanf("%d%d",&a,&b);
c=a+b; //操作
printf("%d\n",c);
fclose(stdin);fclose(stdout); //将输入、输出文件关
return 0; //结束程序
}
【标程】
#include <iostream>
#define MONTH 300
using namespace std;
int main()
{
int change=0,cost,bank=0;//结余，预算，存款
for (int i=1;i<=12;i++)//从1月~12月
{
cin>>cost;//输入
change+=MONTH-cost;//得出本月结余
if (change>=100)//如果本月结余可以存款
{
bank+=change/100*100;//存款累计
change%=100;//求出存款后的结余
}
if(change<0)//当结余出现负数时
{
cout<<"-"<<i<<endl;//输出
return 0;
}
}
cout<<bank*(1+20*1.0/100)+change<<endl;//输出月末钱
return 0;

#include<bits/stdc++.h> using namespace std; int main(){ int arr1[13];//数组越界问题 int sum=0,a=0,c=0; for(int i=1;i<=12;i++){ cin>>arr1[i]; } for(int i=1;i<=12;i++){ if(i==1){ a=300-arr1[i];//剩余的钱 if(a<0){ cout<<"-1"<<endl; break; }else{ sum+=(a/100)*100;//存的钱 c=a-((a/100)*100);//除去存的钱之外，还剩下多少钱? } } } for(int i=2;i<=12;i++){ a=300-arr1[i]+c; if(a<0){ cout<<"-"<<i<<endl; break; }else{ sum+=(a/100)*100; c=a-((a/100)*100); } if(i==12){ cout<<sum*1.2+c<<endl; } } return 0; }这个题不是很难理解，但是一直想不通不能AC，
困扰我一两天，突然突发奇想，是不是数组的空间不够啊，
改了下，果然成功了，心态崩了 -
