#include <bits/stdc++.h>
using namespace std;
int main(){
  int n,k;
    double sum1=0,sum2=0,ans1=0,ans2=0;
    cin>>n,k;
    for(int i=1;i<=n;i++)
    {
        if(i/k==0) {
            sum1+=i;
            ans1++;
        }
        else 
        {
            sum2+=i;
            ans2++;
        }
    }
    cout<<fixed<<setprecision(1)<<sum1/ans1<<" "<<sum2/ans2;
    return 0;
}

if里边应该用%吧 @quell

@LeNotFound 哦哦好嘟，我试试

by quell @ 2024-09-05 19:31:55

@LeNotFound 可是还是WA鸭

by quell @ 2024-09-05 19:33:19

#include <bits/stdc++.h>
using namespace std;
int main(){
    double sum1=0,sum2=0,ans1=0,ans2=0;
    int n,k;
    cin>>n,k;
    for(int i=1;i<=n;i++)
    {
        if(i%k==0) {
            sum1+=i;
            ans1++;
        }
        else 
        {
            sum2+=i;
            ans2++;
        }
    }
    cout<<fixed<<setprecision(1)<<sum1/ans1<<" "<<sum2/ans2;
    return 0;
}

唔，还是错的

@quell

#include <bits/stdc++.h>
using namespace std;
int main(){
    double sum1=0,sum2=0,ans1=0,ans2=0;
    int n,k;
    cin>>n,k;
    for(int i=1;i<=n;i++)
    {
        if(i%k==0) {
            sum1+=i;
            ans1++;
        }
        else 
        {
            sum2+=i;
            ans2++;
        }
    }
    printf("%.1lf %.1lf",sum1/ans1,sum2/ans2);
    return 0;
}

试试

@quell <<fixed<<setprecision(1)只对后边紧接着的一个输出有效哦

by llhhss @ 2024-09-05 21:11:02

@quell

#include<iostream>
#include<cstdio>
using namespace std;
int n,k,cnt1=0,cnt2=0;
double ans1,ans2,sum1,sum2;
int main(){
    cin>>n;
    cin>>k;
    for(int i=1;i<=n;i++){
        if(i%k==0){
            sum1+=i;
            cnt1++;
        }else{
            sum2+=i;
            cnt2++;
        }
    }
    ans1=sum1/cnt1;
    ans2=sum2/cnt2;
    printf("%.1lf %.1lf",ans1,ans2);
    return 0;
}
