帮写个计算题 一直没写出来


用一百元买一百个蛋，鸡蛋一毛一个，鸭蛋一块五一个，鹅蛋三块一个。请问鸡、鸭、鹅蛋各买多少个
#include <iostream>
using namespace std;
int main()
{
    int x,y,z,ok,M;
    int A,B,C;
    A=x*0.1;
    B=y*1.5;
    C=z*3;
    M=x+y+z;
    cin>>M;
    ok=A+B+C;
    for (x=1;x<M;x++)
    {
         for (y=1;y<M;y++)
        {
              for (z=1;z<M;z++);
            M=x+y+z;
            cout<<x<<"\n"<<y<<"\n"<<z<<endl;
        }
    }
    return 0;
}

为什么不成啊!!!

先上网查一下算法，再写程序。

在线等 ,,,

还是下线等吧

为什么

为什么鸡蛋这么便宜？鸡蛋到底是一块一个还是一毛一个？

看看这个结果是你想要的吗？

/*文件名： BuyEggs.cpp*/
/*用一百元买一百个蛋，鸡蛋一毛一个，鸭蛋一块五一个，鹅蛋三块一个。请问鸡、鸭、鹅蛋各买多少个*/

#include <iostream.h>
#include <iomanip.h>

/*定义价格*/
#define PRICE_EGG    0.1                            /*鸡蛋价格*/
#define PRICE_DUCK_EGG 1.5                /*鸭蛋价格*/
#define PRICE_GOOSE_EGG 3.0                /*鹅蛋价格*/
/*现有金额*/
#define MONEY 100.0

double TotalMoney( int, int, int);    /*统计金额*/

int main()
{
        double money = MONEY;
        int count_egg = 0, count_duck_egg = 0, count_goose_egg = 0;
        int count_max_eggs = ( int)( money / PRICE_EGG);
        int count_max_duck_eggs = ( int)( money / PRICE_DUCK_EGG);
        int count_max_goose_eggs = ( int)( money / PRICE_GOOSE_EGG);
        //cout << count_max_eggs << " " << count_max_duck_eggs << " " << count_max_goose_eggs << endl;                /*打印可以买到的鸡蛋数量*/
       
        for ( ; count_egg < count_max_eggs; count_egg++)
        {
            for ( count_duck_egg = 0; count_duck_egg < count_max_duck_eggs; count_duck_egg++)
            {
                for ( count_goose_egg = 0; count_goose_egg < count_max_goose_eggs; count_goose_egg++)
                {
                    if ( TotalMoney( count_egg, count_duck_egg, count_goose_egg) == MONEY)
                    {
                        cout << "鸡蛋 " << setw(3) << count_egg << " 个,"
                        << "鸭蛋 " << setw(3) << count_duck_egg << "个,"
                        << "鹅蛋 " << setw(3) << count_goose_egg << "个" << endl;   
                    }   
                }   
            }   
        }
}


double TotalMoney( int eggs, int duck_eggs, int goose_eggs)
{
    double total = PRICE_EGG * eggs + PRICE_DUCK_EGG * duck_eggs + PRICE_GOOSE_EGG * goose_eggs;   
   
    return total;
}

这是完整的结果。

#include"iostream"
using namespace std;
void main()
{
    int x,y,z;
    float m;
    for(x=0;x<100;x++)
        for(y=0;y<=66;y++)
            for(z=0;z<=33;z++)
            {
                m=0.1*x+1.5*y+3.0*z;
                if(m==100&&x+y+z==100)
                    cout<<"鸡蛋的个数为"<<x<<"个   "<<"鸭蛋的个数为"<<y<<"个   "<<"鹅蛋的个数为"<<z<<"个   "<<endl;
            }
}
运行结果为：
鸡蛋的个数为40个  鸭蛋的个数为56个  鹅蛋的个数为4个
鸡蛋的个数为55个  鸭蛋的个数为27个  鹅蛋的个数为18个

好像不止两种结果吧？
