@xyy20110721 a数组应为double类型

by ISTP @ 2022-08-18 14:01:02

数组要开float或double类型的，不然算好的小数存进去小数位会自动舍弃掉

开double类型数组

@xyy20110721 拿你的改的，A了

#include<iostream>
using namespace std;
int main()
{
    double a[11];
    int i,s;
    for(i=1;i<=10;i++)
    {
        cin>>a[i];

    }
    a[1]*=28.9;
    a[2]*=32.7;
    a[3]*=45.6;
    a[4]*=78;
    a[5]*=35;
    a[6]*=86.2;
    a[7]*=27.8;
    a[8]*=43;
    a[9]*=56;
    a[10]*=65;
    printf("%.1f",a[10]+a[1]+a[2]+a[3]+a[4]+a[5]+a[6]+a[7]+a[8]+a[9]);
    return 0;
}

这是我的AC代码，简单粗暴，不用动脑：

#include<bits/stdc++.h>
using namespace std;

int main(){
    int arr[10];
    double sum=0;
    for(int i=0;i<10;i++){
        cin>>arr[i];
        if(i==0){
            sum+=28.9*arr[i];
        } 
        else if(i==1){
            sum+=32.7*arr[i]; 
        }
        else if(i==2){
            sum+=45.6*arr[i];
        }
        else if(i==3){
            sum+=78*arr[i];
        }
        else if(i==4){
            sum+=35*arr[i];
        }
        else if(i==5){
            sum+=86.2*arr[i];
        }
        else if(i==6){
            sum+=27.8*arr[i];
        }
        else if(i==7){
            sum+=43*arr[i];
        }
        else if(i==8){
            sum+=56*arr[i];
        }
        else if(i==9){
            sum+=65*arr[i];
        }

    }
    printf("%.1lf",sum);
    return 0;
}
