for循环格式是:   for(initial;condition;operation)
                  {
                       Statements;
                   }
本人遇到的问题是例如:一：   {                                    二：{
                             ...                                       ...
                             for(int i=0;i<array.Length;i++)           for(int i=0;i<4;i++)
                             Console.Write(array[i]);                  {
                             Console.WriteLine();                         for(int j=0;j<4;j++)
                             ...                                          {
                             }                                               ...
                                                                           }
                                                                         }
问题是为什么情况一没有for()
                        {
                          statements;
                         }结构 既是for()后并没有{statements;}
                               一二两者的区别是什么？什么时候用需要{statements;}？
我是新手谢谢赐教！
