What is the size of an activation record for the function **f(****)**? How did you find out?

```
#include <stdio.h>
int K = 1024;
main(int argc, char *argv[])
{
int n;
int f() ;
if (argc != 2) exit(-1);
n = atoi(argv[1]);
printf("Address of:\n K=%x \n main=%x \n argc=%x \n argv=%x \n");
printf ("n=%x \n f=%x \n printf=%x \n", &K, &main, &argc, &argv, &n, &f);
f(n) ;
}
int f(int n)
{
int *m;
static int s;
m = (int*)malloc(K*sizeof(int));
printf("f(%d) starts \n n=%x \n m=%x \n s=%x \n *m=%x \n", n, &n, &m, &s, m);
if(n>0) f(n-1);
printf("f(%d) returns\n", n);
return;
}
```

Can any one explain that?
