Pointer comptability

#include <stdio.h>

int main(void)
{
  double x = 1.1, y;
  int  *p;

  /* assign p (an integer pointer) to point to a double. */
  p = (int *) &x;

  /* The next statement does not operate as expected. */
  y = *p; /* attempt to assign y the value x through p */

  /* The following statement won't output 1.1. */
  printf("The (incorrect) value of x is: %f", y);

  return 0;
}
