百元百鸡问题

100快钱，买100只鸡。公鸡3元，母鸡2元，小鸡一元2只。问：各买多少只？用C++程序编写出来，怎么写？

#include<stream.h>
int main()
{
float x,y,z;
for(x=0;x<30;x++)
for(y=0;y<50;y++)
for(z=0;z<10;z=z+2)
if(100==3*x+2*y+z*1.0/2)
cout<<"x="<<x<<" y="<<y<<" z="<<z<<endl;
}

#include <iostream>

using namespace std;

int main()

{

int gj,mj,xj;

for (gj = 0;gj <= 33;gj++)

{

for (mj = 0;mj <= 50;mj++)

{

xj = 100 - gj - mj;

if (xj % 2 == 0 && gj * 3 + mj * 2 + xj / 2 == 100)

cout << "公鸡" << gj << "\n母鸡" << mj << "\n小鸡" << xj << endl;

}

}

return 0;

}

程序说明与注释 #include<stdio.h> int main() { int x,y,z,j=0; printf("Folleing are possible plans to buy 100 fowls with 100 Yuan.\n"); for(x=0;x<=20;x++) for(y=0;y<=33;y++) { z=100-x-y; if(z%3==0&&5*x+3*y+z/3==100) printf("%2d:cock=%2d hen=%2d chicken=%2d\n",++j,x,y,z); } } 一定要采纳那
