哪里出了问题

晕~你这连套了两个死循环唉~~~
这样改：
void main()                                                                  
{                                                                             
int cocks=0,hens,chicks;                                                      
while(cocks<=19)                                                              
                                                                              
{                                                                             
hens=0;                                                                       
while(hens<=33)                                                               
{                                                                             
chicks=100-cocks-hens;                                                        
if(5.0*cocks+3.0*hens+chicks/3.0==100)                                       
printf("%d %d %d\n",cocks,hens,chicks);                                       
hens++;
}                                                                             
 cocks++;                                                                     
}                                                                             
                                                                  
}

谢谢你老大

#include<stdio.h>
void main()
{
  int cocks,hens,chicks,i,j,k;
  for(cocks=1;cocks<=100;cocks++)
    for(hens=1;hens<=100;hens++)
       for(chicks=1;chicks<=100;chicks++)
          if(5*cocks+3*hens+chicks/3==100)
             { britf("%d %d %d",cocks,hens,chicks);break;}



}

楼上的在浪费资源。
