Hi friends,  Today I am going to tell you a trick in C++ by which you can turn on/off the num lock button and led as well on your keyboard.

If you are a C++ programmer then I am sure that you will like this post.

Steps:

1. Open C++(any compiler).

2. Copy and paste the following code.

#include<stdio.h>

void main()

{

char far *kb;

kb=(char far *)0x417;

}

3. Compile and run the program.

Compilation process may differ according to your compiler.
