A pointer to pointer variable can hold the address of another pointer variable. The Syntax is as follow: type** variable; Example:: //function prototype void func(int** ppInt); int main() { int nvar=2; int* pvar=&nvar; func(&pvar); .... return 0; }
One more important use of pointer-to-pointer is for creating multi-dimensional array dynamically, see See the related links.
No. Each laser pointer uses a laser that emits a specific color. the only way to get a different color would be to get a different laser.
Void pointer can hold the address of any kind of pointer. But we can't operate on void pointer
A pointer to pointer has many uses, one of the simplest being 2D arrays (matrices). Compacting garbage collectors also often employ pointer pointers.
Accessing data by address.

it uses pointer to stucture.
As the name suggests Pointer is used to point towards something ,here in this case it points to another variable and stored at a memory location. Pointer is a variable that stores address of another variable. Different Types of pointers are: 1)Dangling Pointers 2)NULL Pointers 3)This Pointer 4)Generic Pointer 5)Near Pointer 6)Far Pointer
Yes. A built-in pointer uses the built-in increment operator. The implementation of this operator increments the pointer variable's value by the length of the pointer (in bytes). The pointer's length is determined by the underlying type of the pointer itself, not the type of the object being referred to. Thus a built-in pointer may refer to a user-defined type (struct or class).
Clarification is needed. The pointer used isn't specific to the Bar Mitzvah ceremony, it is the pointer used whenever the Torah scroll is read. The pointer itself is called a 'yad' which means 'hand'.
