To make a 0-99 The counter of ,P1.7 Connect the button ,P2 Connected to nixie tube section , Common anode digital tube ,P3.0,P3.1 Connect the nixie tube bit code , Every time you press the key , Nixie tube display plus one . Please write down the of SCM C51 Code 

#include "reg51.h"
#include "stdio.h"

sbit in1  = P1^7;
sbit lse1 = P3^0;
sbit lse2 = P3^1;


typedef unsigned int u16;


unsigned char code SMG_duanma[11] = {
    0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90,0xff};
void delay(u16 i)
{
    
    while(i--);
}

void xianshi(int a,int b,int o)
{
      		   P2=0xff;
		   lse1 =0;
		   lse2=1;
		   P2=SMG_duanma[a];
		   delay(1000);
		   P2=0xff;
		   if(o==1)
		   {
    
		   lse1 = 1;
		   lse2 = 0;
		   P2=SMG_duanma[b];
		   delay(1000);
		   }
	 	   P2=0xff;
}
void main()
{
    

  int i=0;
  int b=0;
  int c=0;
 while(1)
 {
    
  if(in1==0)
  {
    	  
    delay(100);
    if(in1==0)
       {
     
	   while(in1==0);
	   i=i+1; 
	   while(in1!=0)
	   {
    
	   if(i<10)xianshi(i,0,0);
	   if(i>=10)xianshi(i%10,i/10,1);
	   if(in1==0)break;

	   }
	   P2=0xff;
