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.
Discard these after the date on the package and donât store them on the door where itâs warmer. Milk should be ok to drink 7 to 10 days after the sell-by date as long as you keep it cold, Bruhn said. Soft cheeses are ok to eat up to a week, while hard cheeses can stay good for 3 or 4 weeks.
