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. When we define a pointer to a pointer, the first pointer contains the address of the second pointer, which points to the location that contains the actual value as shown below.

27.03.2022 · 1) Void Pointer in C A pointer is said to be void when a pointer has no associated data type with it. In other words, it can point to any data type and also, it can be typecasted to any type. Since a void pointer does not have any standard type (data type) it is also referred to as a generic pointer sometimes.

pointer = x (which may be what you intended to write) changes where pointer points to. If x is a pointer, then they now point to the same location in memory. This is different from *pointer = *x (also a possibility), as the latter creates a copy of whatever's in x , whereas the former causes them to both point to the same value, meaning changes to one affect the other.
