7．百錢買百雞。用100元錢買100只雞，公雞每只5元，母雞每只3元，小雞沒3只1元，要求每種雞至少買一只，且必須是整數(shù)只，問公雞、母雞和小雞各買幾只？#include<iostream.h>main(){?int?cock,hen,chicken;for(cock=1;cock<16;cock++)for(hen=1;hen<29;hen++){ chicken=100-cock-hen;if(5*cock+3*hen+chicken/3==100 &&?chicken%3==0){?cout<<"cock="<<cock<<" ";cout<<"hen="<<hen<<" ";cout<<"chicken="<<chicken<<endl;}}}不是很懂代碼思路····（小白一枚）
