题目描述

实验
还没学到一些代码，导致做了1个多小时也不知道为什么输出不了，但是除了输出部分前面的思路还是都对的，还是缺少积累。

样例

#include<bits/stdc++.h>
using namespace std;
int main()
{
    int n,q=0,w=0,e=0,sum;
    cin>>n;
    for(int i=1;i<=n;i++)
    {
        char s;
        cin>>sum>>s;
        if(s=='C')
        {
            q+=sum;
        }
        if(s=='R')
        {
            w+=sum;
        }
        if(s=='F')
        {
            e+=sum;
        }
    }
    int tot=q+w+e;
    cout<<"Total: "<<q+w+e<<" animals"<<endl;
    cout<<"Total coneys: "<<q<<endl;
    cout<<"Total rats: "<<w<<endl;
    cout<<"Total frogs: "<<e<<endl;
    cout<<"Percentage of coneys: "<<fixed<<setprecision(2)<<(double)q/tot*100<<" %"<<endl;
    cout<<"Percentage of rats: "<<fixed<<setprecision(2)<<(double)w/tot*100<<" %"<<endl;
    cout<<"Percentage of frogs: "<<fixed<<setprecision(2)<<(double)e/tot*100<<" %"<<endl;
    return 0;
}
