Why Use Pointer To Pointer. It is a variable that points to a data type (like int or string) of the same type and is created with the * operator. Syntax of a pointer in c++: A pointer variable can store the address of any type including the primary data types, arrays, struct types, etc. If you want to use a function to modify a thing, be it an object or an address (pointer), you have to pass in a pointer to that. Likewise, a pointer can store the. Data_type_of_pointer *name_of_variable = & normal_variable; In c++ a pointer is a variable that is used to store the memory address of other variables. A pointer can be used to store the memory address of other variables, functions, or even other pointers. Pointers to pointers, or double pointers, are variables that store the address of another pointer. In essence, they add another level of indirection. For example, when you wish to modify the value (address pointed to). A pointer to a pointer is a form of multiple indirection or a chain of pointers. Normally, a pointer contains the address of a variable.
