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.
Frozen breast milk will last about two weeks if stored in the freezer door, where it's subject to frequent blasts of warm air. Frozen milk will last up to four months if stored in a separate compartment inside your freezer. If stored in a deep freeze at 0 degrees or less, your milk will keep for up to six months.
