code_with_pointers.cpp:
Running this produces something like
Enter divisor: 93
After dividing by 93, some number is 1.07527e+28
Address of some_number: 80987ffcd4
... and its pointer: 80987ffcd4
Value pointer's value: 80987ffccc
What value pointer points *at*, before multiplying: 7
7 times 8 = 56
Note you will often get a different address on each run because putting
data at the different addresses increases security.
