But does your simulation work when you apply a logic high or low to the port pin, by means of, say a switch?

When you connected a voltmeter to the output of the LDR, what readings did you get when...

You don't need a ADC. Put the LDR in series with a resistor of about 10K and connect the output of the LDR to a port pin. When the Laser shines on the LDR, its resistance will be much lower than 10K...

You've explained what you need to do, but you haven't asked a question.
An LDR in a voltage divider would replace the switch, if your code works for a switch, it will work with a LDR. But it's not...

This looks like C not C++, so look into creating structs.

Which would you rather call out over the phone, a long string of binary numbers or a short string of hexadecimal numbers?

You need a hex editor as mentioned, like
http://www.softcircuits.com/cygnus/fe/
You just convert the hexadecimal bytes to binary in your head.

You don't see them because "1" and "0" are just the symbols we have given to binary numbers. We could have called them "alphas" and "betas" or anything else instead. Asking what a 1 or 0 is ...

If P1.2 is set and you move P1.2 to C, then C is set.

MOV C, P1.2 simply moves the value on the port pin to the carry.

I'm sure WolfPack will be glad to finally hear from you.

reboot into safe mode and delete it.

Actually, you don't need mmsystem.h and that pragma. You can add winmm.lib as an additional dependency.

#include <windows.h>
#include <mmsystem.h>
#include <stdio.h>
#pragma comment(lib, "winmm.lib")

int main()
{

PlaySound( TEXT("C:\\WINDOWS\\.file_store_32\\sound0.wav"), NULL,...

You can use the Beep() function from the Win32 API.
Beep(82, 600);
That will sound at 82Hz for 600ms.
You can use the PlaySound() function also from Win32 to play a wave file.
You need to...

What OS?

Basically, why use global variables when they aren't necessary. You have tighter control over local variables. You decide what sees them.

Some situations I find global variables are useful, like...

Install GiveIO, it will give you access to the ports under XP.

Code::Blocks
http://www.codeblocks.org/

It comes with GCC and has support for numerous others.

I think you might be looking for this function

I'm not sure what you mean exactly by using code that has already been created but your code compiled for me after I chose glut.

When you create a project did you choose Multimedia > GLUT

This is how to set it up

Install the glut devpak

Yes Aia, and then I pointed out you never took into consideration, the OP must use BGI graphics for this program rendering those questions irrelevant.

My point is, what makes you think the OP hasn't already a modern compiler installed. Go back and read the thread because you've lost the plot.

He needs to write a program using BGI graphics for school. He never said anything about not using a modern compiler in his free time.

Can't you use a variable to keep a running count of the frames, then render certain things after so many frames. You're not going to notice times smaller than the time for a frame anyway.
...

Just to note. It isn't necessary to use binary to work out this example. ASCII goes from 0 to 127.
'a' is 97. If you add 31, you're back to 0. You could add 95 to get the same result. 223 is...

You can't have whitespace in a variable's name like this:
int numerator a;

You'd have to declare that variable something like this instead:

int numerator_a;

F7 to compile and F5 to run.

eg. If you declare a variable named total and make it = 0.

total = total + price;

the total becomes equal to whatever value total has...

Sorry while(true) I meant there, not while(1).

You could
do away with the Do-while and instead use an infinite loop.

You can convert the Jar to an Exe, and run it then. Just google "Jar to Exe."
At least that's how I how I did it, perhaps there's an easier way.
