A pointer to pointer has many uses, one of the simplest being 2D arrays (matrices). Compacting garbage collectors also often employ pointer pointers.
pointer: to access data by address reference: there is no reference in C language
i would use a laser pointer.
A pointer to a function is the memory address that stores the address of a function, while the pointer itself is a function pointer.A pointer to a function might be defined as "int (*pf)(int, int);", while to actually point to the function, you would use a function pointer, such as "pf = &func;".
because u freakin can
A double pointer has two basic meanings. One is ofa pointer to a pointer, where changing the value ofdouble pointer will result in the original pointer being changed. Another is that of a two-dimentional array, such as a matrix, or a list of char* (e.g. in main when you use argv).
do u have vagina then suck it
Pointer is a variable that stores the address of another variable. Since pointer is also akind of variable, thus pointer itself will be stored at a different memory location.
*
Generic pointer of type 'void *' is compatible with any (data-)pointer, but you cannot use the following operators on it: + - ++ -- += -= * -> []
void pointer
Pointer is a variable that stores address of a variable . A NULL Pointer a pointer that doesn't point to anything, it is a literal zero .Some people ,notably C++ programmers, prefer to use 0 rather than NULL.
The value of a Charles Daly auto-pointer would actually depend on a number of factors. The main factor that would be considered would be the condition of the auto-pointer.
