要求输出如下
    A
   ABA
  ABCBA
 ABCDCBA
ABCDEDCBA
我的代码错在哪了呢
#include <stdio.h>
#include <stdlib.h>
#define  ROWS 5
int main()
{
   int x,y;
   int i=0;
   char A='A';
   for(y=4;y>=0;y--)
   {
                      for(x=0;x<2*ROWS-1;x++)
                      {
                                             if(y<=x||y<2*ROWS-x-1)//处理两边的空格
                                             printf(" ");
                                             else if(y<ROWS)
                                                  {
                                                  printf("%c",A+i);
                                                  i++;
                                                  }
                                                  else
                                                  {
                                                       printf("%c",A+i);
                                                       i--;
                                                  }
                                             printf("\n");
                      }
   }
   system("pause");
   return 0;
}

谢谢你的回复，很实际。确实是这样的。我改成了if(y>x||y<2*ROWS-x-1)，可还是不对。从输出看是printf("\n");的问题，可是我看代码觉得没问题。它应该不是在IF判断语句中。不知为什么

晕，是的。应改为Y〈X
