Got this code snippet from some website:

int num = 1;
if(*(char *)&num == 1)
{
      printf("\nLittle-Endian\n");
}
else
{
      printf("Big-Endian\n");
}

Can anyone explain this step-by-step?

&num -> Adress of a

(char *)&num -> Type-cast address of a into a string

*(char *)&num -> Points to the first character of the string

Am I missing anything here?
