I'm taking CS50 via edx. One of the videos dealing with pointers (can't find it now) runs a program called noswap (under GDB) that highlights how C uses copies of variables (in this case, int a and int b) rather than the variables themselves (in this case, int x and int y).
Toward the end, the video runs "print &a" and receives something like "0xbfffefe4" as the memory location of "int a."
If "a" were a pointer to an int, how would one get the address to which "a" points as opposed to the address at which "a" resides?
Thanks in advance for any help.
