怎么用一個(gè)數(shù)組儲(chǔ)存單片機(jī)四個(gè)引腳的高低電平，程序如下：
#include "reg51.h"

typedef unsigned int u16;
typedef unsigned char u8;

sbit DC0=P1^0;
sbit DC1=P1^1;
sbit DC2=P1^2;
sbit DC3=P1^3;

void delay(u16 i)
{
while(i--);

}
void mian()
{
  P1=0x00;

while(1)
{



   DC0=0;
      DC1=1;
      DC2=1;
      DC3=1;
      delay(200);
         DC0=1;
      DC1=0;
      DC2=1;
      DC3=1;
      delay(200);


      DC0=1;
      DC1=1;
      DC2=0;
      DC3=1;
      delay(200);  DC0=1;
      DC1=1;
      DC2=1;
      DC3=0;
      delay(200);

      }

}
