思路要想一下

#include<iostream>
#include<cstdio>
using namespace std;
int main()
{
    int n;
    cin>>n;
    int c=0,r=0,f=0;
    for(int i=0;i<n;i++)
    {
        int k;
        char t;
        cin>>k>>t;
        if(t=='C') c+=k;
        else if(t=='R') r+=k;
        else f+=k;
    }
    int s=c+r+f;
    printf("Total: %d animals\n",s);
    printf("Total coneys: %d\n",c);
    printf("Total rats: %d\n",r);
    printf("Total frogs: %d\n",f);
    printf("Percentage of coneys: %.2lf %%\n",(double)c/s*100);
    printf("Percentage of rats: %.2lf %%\n",(double)r/s*100);
    printf("Percentage of frogs: %.2lf %%\n",(double)f/s*100);
    return 0;
}
