一些简单的c51程序

#include <stdio.h>
#include <reg51.h>

int a[3] [4]={
        {1,3,5,7},
        {9,11,13,15},
        {17,19,21,23}
        };
        main()
       {
            int i,(*b)[4];
         b=a+1;

		 SCON = 0x50; 
TMOD |= 0x20; 
TH1 = 0xf3; 
TR1 = 1;
TI = 1;

for(i=1;i<=4;b=b[0]+2,i++)
         printf("%d\t",*b[0]);
         printf("\n");
         for (i=0;i<2;i++) {
           b=a+i;
           printf("%d\t",*(b[i]+1));
        }
         printf ("\n");
}
