my code works well in software simulation but it dont work the same way when tried on hardware

this is my code, this piece gets to work well in software simulation but not on the board.how can i get it working on the board??


#include<reg51.h>
sbit party1=P1^0;
sbit party2=P1^1;
sbit result1=P1^2;
sbit result2=P1^3;
sbit display1=P1^4;
sbit display2=P1^5;
sbit display3=P1^6;
sbit display4=P1^7;
void delay(int max)
{
int i=0,j=0;
for(i=0;i<max;i++)
{
for(j=0;j<12345;j++);
}
}
void main()
{
unsigned int temp1=0,temp2=0,count11=0,count12=0,count13=0,count14=0,count21=0,count22=0,count23=0,count24=0;
int a[]={0x3f,0x06,0x5b,0x4f,0xe6,0xed,0x7d,0x07,0xff,0xef};
while(1)
{
// party1=party2=result1=result2=1;
while(party1==0&&party2==1&&result1==1&&result2==1 )
{
temp1++;
}
while(party2==0&&party1==1&&result1==1&&result2==1 )
{
temp2++;
}
count11=count11+(temp1/temp1);
if(count11==9)
{
count12++;
count11=0;
if(count12==9)

}
}

temp1=0;

You will have to post your full code and the Proteus file.
Most likely you have a hardware problem, such as a pin not connected.

This is the full program and can I know what are this Proteus file

Your program did not attach.
Zip it before posting.

"can I know what are this Proteus file"
I assumed you were using Proteus software for your simulation.
Post what you can of your simulation so we can try to recreate what you are doing.
Again ,zip it before posting.
