#include<iostream>
using namespace std;
void main()
{
    for(float a=0.01;a<7.11;a+=0.01)
        {
            for(float b=0.01;b<7.11;b+=0.01)
            {
                if(a+b==7.11)continue;
                else
                    for(float c=0.01;c<7.11;c+=0.01)
                    {
                        if(a+b+c==7.11)continue;
                        else
                            for(float d=0.01; d<7.11;d+=0.01)
                            {
                                float e=a+b+c+d;
                                float f=a*b*c*d;
                                if((e==7.11)&&(f==7.11))
                                {cout<<a<<" "<<b<<" "<<c<<" "<<d<<endl;break;}
                                else continue;
                            }
                    }
            }
    }
                system("pause");
}
这个程序要求4个数相加等于7.11，同时这4个数相乘等于7.11

算法有待改进

求组，有高手能帮忙吗？
我实在是不知道怎么改了
