Can someone help me and explain the source code below, also point out where there is error and correct them for me. The program is to take input from pin0 of port 1 and on a load at pin1 of port1.
Also help me calculate how long the delay function will stay.
I am using AT89S52 microcontroller.
#include<reg52.h>
sbit LED =P1^1
sbit switch =P1^1
int i;
void delay (void)
{
for(i=0;i<100;i++)
}
Void main
{
while (1)
{
switch=1;
{
if(switch=1)
Delay();
LED=1
}
}
}

If there are good programming books please give me.

According to the definition of sbit switch is doesn't.

After correcting this point and additional syntax erorrs, you'll possibly want to make the switch acting on and off.
 

Sorry for the mistake, the sbitswitch should be pin0 of port1. I am more concerned on the delay function, I want to know how long the delay in that program will stay in real life situation. I possible please show me how to calculate the delay in real time.
Also help me write a delay function of 10minutes.
