hey nidhin.k can you explain this section of the code:

 

void Distance_Measure()
{
count=count1=0;
TH0=0x00;TL0=0x00; 
TR0=0;
for(i=0;i<10;i++)         
{
TX=0;           
Delay(1000);
TX=1;           
Delay(10);
TX=0;   
while(RX==0);
TR0=1; 
while(RX==1);
TR0=0;
count=TH0<<8;      
count=count|TL0;    
TH0=TL0=0x00; 
count1=count1+count;
Delay(5000);        
}
count=count1/10;
inch1=count%10000/1000;
inch2=count%1000/100;
result=(inch1*10)+inch2;
 
obj_distance=result-2;  
Lcd8_Decimal3(0XCb,obj_distance); 
 
}
