修改51单片机字符型LCD液晶显示广告牌控制使SHEN ZHENG滚动！！！代码如下！！

#include<reg51.h>
#include<INTRINS.H>
sbit RS=P2^0;
sbit RW=P2^1;
sbit E=P2^2;
void lcd_w_cmd(unsigned char com);
void lcd_w_dat(unsigned char dat);
unsigned char lcd_r_start();
void int1();
void delay(unsigned char t);
void delay1();
void main()
{
unsigned char lcd[]="SHEN ZHEN";
unsigned char i;
P1=0xff;
int1();
delay(255);
lcd_w_cmd(0x83);
delay(255);
for(i=0;i<9;i++)
{
lcd_w_dat(lcd[i]);
delay(200);
}
while(1);
}
void delay(unsigned char t)
{
unsigned char j,i;
for(i=0;i<t;i++)
for(j=0;j<50;j++);
}
void delay1()
{
_nop_();
_nop_();
_nop_();
}
void int1()
{
lcd_w_cmd(0x3c);
lcd_w_cmd(0x0e);
lcd_w_cmd(0x01);
lcd_w_cmd(0x06);
lcd_w_cmd(0x80);
}
unsigned char lcd_r_start()
{
unsigned char s;
RW=1;
delay1();
RS=0;
delay1();
E=1;
delay1();
s=P0;

return(s);
}
void lcd_w_cmd(unsigned char com)
{

i=i&0x80;
delay(2);
}while(i!=0);

}
void lcd_w_dat(unsigned char dat)
{

Answer 1

for(i=0;i<9;i++)
{
lcd_w_dat(lcd[i]);
delay(200);
}
while(1)
主程序里面 一个while（1）；单独一句。你想一下，这句会发生什么后果？
