Techniques for ratchet pointers in computing hardware are described. The technology includes a memory to store an object referenced by a ratchet pointer, and a processor to provide access to a slice of the object by decrypting a base address and a limit of the ratchet pointer, generating a ...
In computing how many bytes to allocate, the sizeof operator is useful: Given a type, the sizeof operator computes how many bytes a value of that type requires. So sizeof(int) would be 4 on most computers (but on some computers it may be 2 or 8), and sizeof(struct Point) would ...
5Pointer to Pointer C++ allows you to have pointer on a pointer and so on. 6Passing Pointers to Functions Passing an argument by reference or by address both enable the passed argument to be changed in the calling function by the called function. ...
pointers are not a necessary tool. However, I'm going to cover them now rather than later in this series because they are closely related to arrays, which we discussed in theprevious article. Also, pointers help to reinforce our understanding of the relationship between code and hardware. ...

Definition of Pointer in C Every variable is stored in some memory location, and that memory location has an address. A pointer is a variable that stores the memory address of variables, functions, or other pointers. A pointer is a derived data type that can store the memory address of oth...

The problem is: let's say there's an array aa and an associative operation ∗∗ and we are interested in computing f(l,r):=al∗al+1∗…∗arf(l,r):=al∗al+1∗…∗ar , where we want to be able to increment ll or rr and easily recompute ff. If we can do that...
Andrei Alexandrescu discusses smart pointers, from their simplest aspects to their most complex ones and from the most obvious errors in implementing them to the subtlest ones—some of which also happen to be the most gruesome.
the fixed one-element array in the classManagerdoesn't look very impressive, but as a demonstration, it gets the point across. The manager not only manages the distribution of computing tasks, but also provides an abstract layer for notifying the user: instead of outputting to a log, it can...
