just know 3 things: 1  Pointer is a variable that store the address of another variable (or just any address). * 2  is used to get the value at the memory location that is stored in the pointer variable. & 3  operator gives the address of a memory location.sually what I do is represent memory as a grid, so that I can make up addresses, highlight different memory spaces and write in the cells values (or even further, their binary representations) and link the pointers in memory to the values they point at.
The accepted rule of thumb is that if you're properly refrigerating it, your carton of whole milk's expiration date is five days after the sell-by date.
Milk can generally last up to two weeks if constantly refrigerated. Look on the tab of the milk carton and it will say: Best before________. This DOESN'T mean the milk is not good for a couple of more days, but they are saying it will taste the best before that date. Dana Mccullough.
