可以参照此写法

#include<cstdio>
using namespace std;
int main()
{
    int electricity;
    double electricity_price;
    scanf("%d",&electricity);
    if(electricity<=150)
    {
        electricity_price=electricity*0.4463;
    }
    else if(electricity>150&&electricity<=400)
    {
        electricity_price=150*0.4463+(electricity-150)*0.4663;
    }
    else
    {
        electricity_price=150*0.4463+250*0.4663+(electricity-400)*0.5663;
    }
    printf("%.1f",electricity_price);
    return 0;
}
