A pointer is a special kind of variable in C and C++ that holds the address of another variable.
Pointers and arrays are two sides of the same coin. To write any kind of non trivial application in C, pointers are needed.

In computer science, a pointer is a programming language data type whose value refers directly to (or "points to") another value stored elsewhere in the computer memory using its address. For high-level programming languages, pointers effectively take the place of general purpose registers in low-level languages such as assembly language or machine code, but may be in available memory.
