Incrementing pointer (ptr++) and (*ptr++)

Question

I was revisiting pointers when I had this doubt.

int *ptr;
int arr[5] = {10,20,30,40,50};
ptr = &arr[0];

Now printf(\"Value: %d\"

Answer 1

The order of C Precedence from high priority:

()
++
* & for pointers
* /
+ -

so,

 *ptr++ equivlant to *(ptr++)
 ++*ptr equivlant to ++(*ptr)

and for this line *ptr++; it will only increment the ptr pointer.
