求c51长辈纠正一下代码#c51

#include"reg52.h"
sbit k=P3^0;//缘由https://ask.csdn.net/questions/7952938
unsigned char code SmZiFu[]={63,6,91,79,102,109,125,7,127,111,128,0};//0-9.
void main()
{
	unsigned char y=0,m=0,z=0,x=0;
	while(1)
	{
		if(++y==0)
		{
			P1=0;P0=0xff;
			if(k)//按键未按数码管显示
			{
				if(x==0){
				P1=SmZiFu[z%10];
				P0=255-0x01;}
				if(x==1){
				P1=SmZiFu[z/10];
				P0=255-0x02;}
				if(++m==0)if(++z==11){z=0;P2=~P2;}//数码管显示10间隔LED闪烁
			}
			else P2=0;//按键按下清零
			if(++x>1)x=0;
		}
	}
}
