用break/continue语句 百钱百鸡。公鸡5元一只，母鸡3元一只，小鸡1元3只。求100元分别能买多少公鸡、母鸡、小鸡。



           int x, y, z;        //x：公鸡，y:母鸡，z:小鸡
            bool flag = false;
            x = y = z = 0;
            for(x=1;x<100/5;x++)
            {
                for(y=1;y<100/3;y++)
                {
                    z=100-x-y;
                    if (z % 3 == 0 && x * 5 + y * 3 + z / 3 == 100)
                    { flag = true; break; }                  //这里break语句跳出最内一层循环
                }
                if (flag)
                    break;                              //这里break语句跳出最外一层循环
            }
            Console.WriteLine("Cook={0},hen={1},chick={2}", x, y, z);
            Console.Read();
