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.
You can expect the milk to remain good for 5 to 7 days after that, as long as it has been stored properly and has been kept bel â¦ ow 40Â°F. Since the milk is being cooked, if it doesn't smell, hasn't curdled and is just a few days past the sell by-you shouldn't have any problem.
