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.
Question: My teenage daughter refuses to drink milk after the sell by date on the carton, but Iâve always felt it was safe for at least a few days after that. Can you drink milk after the sell-by date? Answer: Yes, milk that has been properly stored will generally remain drinkable for about one week after the sell-by date on the package. Thatâs the general case, mind you â as the Dairy Council of California points out, several factors will influence what happens in your particular fridge once the milkâs sell-by date has passed.
