这个C51程序少了什么?

/*  下面我写的这个C51程序少了什么?   */

 

#include<reg52.h>

#define uchar unsigned char
#define uint  unsigned int

   code uint  design[]=
         {
              0xff,0xfe,0xfd,0xfb,0xe7,0xef,0xdf,0xbf,0x7f,
              0x7f,0xbf,0xdf,0xef,0xe7,0xfb,0xfd,0xfe,0xff,
              0xff,0xfe,0xfc,0xe0,0xc0,0x80,0x00,0xe7,0xdb,
              0xbd,0x7e,0xff
         };
  void delay_ms(uint x)
        {
            uchar t;
            while(x--)
            for(t=0;t<120;t++);

   //  --完--

/*   对, 少了while循环语句, 似乎违章, 你用Proteus仿真运行一下,  看看如何?  有点意思.
