@zch120526 《输出格式》《包含一个实数》《精确到小数点后一位》

要保留小数点后1位，下次记得看输出格式@zch120526

@zch120526 《后一位》

by BlackWuKong @ 2024-08-19 19:10:36

@zch120526 我的思路：

#include<bits/stdc++.h>
using namespace std;
int main(){
    double p[110]={0,28.9,32.7,45.6,78,35,86.2,27.8,43,56,65},m=0;
    int a;
    for (int i=1;i<=10;i++){
        cin>>a;
        m+=a*p[i];
    }
    printf("%.1lf",m);
    return 0;
}

我的思路：

#include<bits/stdc++.h>
using namespace std;
int main(){
    float a[10]={28.9,32.7,45.6,78,35,86.2,27.8,43,56,65},x=0;
    int i,n;
    for (i=0;i<10;i++){
        cin >> n;
        x+=n*a[i];
    }
    cout << x*1.0;
}
