Programming is all about hacking . Hacking in good sense means tinkering the code for achieve great things.

So here is a small hack in C using which you can copy one array into another array without using any loops!!!! and obviously without using any in built in functions.

#include
int main()
{
static int i=0; //array index
int a[10]={1,2,3}; //first array
int b[10]; //second array
b[i]=a[i];
printf("\n %d",b[i]);
i++;
if(i>2) exit(0); //continue till first array is empty
main();
}

The hack uses the two simple facts of C

  1. A static variable will not be re initialized when a function is called

  2. main ( ) is a user defined function

Do you have any better hacks? Let me know!
