百钱买百鸡

中国古代数学家张丘建在他的《算经》中提出了一个著名的“百钱买百鸡问题”：一只公鸡值五钱，一只母鸡值三钱，三只小鸡值一钱，现在要用百钱买百鸡，请问公鸡、母鸡、小鸡各多少只？

package program1;
//百钱买百鸡:一只公鸡五钱，一只母鸡三钱，三只小鸡一钱
//公鸡:cock,母鸡:hen,小鸡:chicken
public class ch01 {

 public static void main(String[] args) {
  // TODO Auto-generated method stub
  int cock;
  int hen;
  int chicken;
  for( cock = 0 ; cock <= 20 ; cock ++ )
  {
   for( hen = 0 ; hen < 33 ; hen ++ )
   {
    for(chicken = 0 ; chicken <= 100 ; chicken ++ )
    {
//     if((coke + hen + chicken == 100) && (5 * coke + 3 * hen + chicken / 3 == 100))
//犯错1；chicken / 3 是对3取整，类型不对，应为小数     
     if((cock + hen + chicken == 100) && (5 * cock + 3 * hen + chicken / 3.0 == 100))
     {
      System.out.println("母鸡："+ cock + "公鸡：" + hen + "小鸡：" + chicken);
     }
    }
   }
  }
 }

package program1;
//百钱买百鸡:一只公鸡五钱，一只母鸡三钱，三只小鸡一钱
//公鸡:cock,母鸡:hen,小鸡:chicken
public class ch011 {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
                int cock ;
                int hen  ;            
                for( cock = 0 ; cock <= 20 ; cock ++ )
                {
                    for( hen = 0 ; hen < 33 ; hen ++ )
                    {    
                        int chicken = 100 - cock - hen;
                        if(5 * cock + 3 * hen + chicken / 3.0 == 100)
                        {
                            System.out.println("母鸡："+ cock + "公鸡：" + hen + "小鸡：" + chicken);
                        }
                        
                    }
                }
    }
